Moroso Trick Front Spings

[Dubuick]

Does anyone run trick spings. Just woundering which of the four offered work best and if anyone as any pictures of your car ride height and /or part numbers of the sping you used would be great .I don't want deal with putting spings in that i have to take out and cut ( my freind with a mustang had to do that ) and I like the ride height of the car and want to keep it the same. Any help would be great

Mike,

I used the Morroso (spelling?) trick springs in this (http://www.v8buick.com/showthread.php?s=&threadid=17982&highlight=mass+buick) car with 70/30 shocks and it launched VERY well, in my opinion. I'd have to dig up my old paperwork to see exactly which set I used but I don't remember having to cut anything....now that I think of it, I believe they were the small block set....

Take a look at the pics and see for yourself....

I'm thinking the 47190's would be good.
At 3750 lbs your car is probably a bit heavy for the 47160's.

[RACEBUICKS]

I took mine out and installed the stock AC springs and the 60 foots got better!!!:Do No:

[GS Kubisch]

I wouldn't exactly write that in stone............

[RACEBUICKS]

Its the truth Can you explain it?? I cant. Since I took them out my car has dropped into the 1.46 's and before the best was 1.52

[Dubuick]

I have reading up on them more and the 710-47190 spings are
for front end weights of 1680-1750. Now does that mean i drive the car half way on the scale to get the front end weight . and also i thinking the weight of my car should be down to around 3550 to 3600 next year ( get glass bumpers and hood and getting rid of all the little things i doing need in the car anymore)
Kubisch what do you run in the front of your car for spings?

[GS Kubisch]

mine are the 47160's......I actually cut some off to get my desired ride height.(I like low cars,The lower the better).
Now that you mention weight reduction I might lean toward the 160's on your car.

Mike, there are alot of things that could go into that, and most not good. Anytime you make a change against proven engineering practice and you get an improvement, you need to investigate further. You may have just uncovered another problem.

You basically "tied-down" the front end and killed some weight transfer. This could be a result of your Instant Center Location, or something more obscure. You may have been wadding up the tires with the Moroso springs causing mild "tire shake". I've been there before.

You may have a problem with shock settings, too.

Another point - when and where did you pick-up 60'? Did you test at the same track, under same or corrected conditions, with NO other changes to the car? Did you use a different tire pressure? Little things matter.

The term "I can't explain it, but it works" shouldn't be in a racer's vocabulary. There is a scientific reason for EVERYTHING that happens in a racecar. I'm not trying to be harsh, just honest.

Just trying to help. Have fun.

PS - I prefer the 47160's unless, like Gary said, you have a heavy nose. More front travel (lower ride height) typically relates to quicker ET's in a stock suspended A-body with a proper set-up. IMHO

[RACEBUICKS]

Jeff since I have noone in my area that can help me I have been contemplating taking the car to a chassis shop and spend some money to help me get the car better. (without cutting anything up) BUt I may have another plan just to give up on the tanker GS and go into another car altogether. Im really sick of trying to make it run a number. I may not bring it to BG just for that reason. I have another car bought and I am negotiating on a C.M. tube car so I can throw the body off and install a Buick body over it. I have noone to help me around here and even less people around that know anything about Buicks let alone taking a big heavy one in the 9s............

[Smartin]

Let me know if you decide to sell that big heavy tanker:Brow:

[Rodster]

Does anyone run the trick springs on a primarily street car?My Stage 2 headed GS has poor weight transfer (and thus poor traction) but handles really well with the present setup.I do not want to drive a pogo stick most of the time.Would appreciate hearing your experiences with street use.Thanks-Rod

[RACEBUICKS]

I ran them around town for years with no problems on my car as an 11 second car. I didnt try to slide thru the corners with them however..............

[Jeff Kitchen]

Gee, Mike I didn't mean to invoke any life changing decision here. You can put your car in the 9's, you just need to work at it a little more. You may just need to contact someone like Dick Miller or Alf Weibe and buy a suspension package and use their set-up and get their advise. You might also read Dave Morgan's "Doorslammers: the chassis book". Remember, our A-bodies are basically 4-links with a few twists. The book may unlock some ideas for you. And don't think a tube chassis car with a 4-link is any easier. I've known people that got "lost" with their chassis, and some never got back. I think any chassis needs a 4 wheel scale session once-in-a-while to keep things in check. You might want to do that now.

Keep trying. Have fun.

Gary do you have a picture of your car just sitting on flat gound just want to see the ride i to like the car low to ground .The sping i have now in the car are trick spings but there were taken out of a super stock GS back in 1982 and been in my car ever since so there very worn out but as a awsome rake to it..

[GS Kubisch]

No problem.....Let me know if you'd like another.This is about the only still/side photo but I have some ather angles too.

[Dubuick]

I like that your car sits nice!! now you said you cut the spings right?how much? also what size front tire is that?:3gears:

[dryskip]

Mike D., what can you tell me about your rear tire/wheel combo? I'm considering new rubber for my '68. TIA

[GS Kubisch]

Mike
I pretty sure it was about 1/2 of a coil I removed.It's been awhile.
Front tires are Moroso ''7.10x15''.They measure 27'' tall.
I've been kicking around the idea of a 26'' tire but I don't know that I'll ever get around to it.

[Dubuick]

dryskip said:Mike D., what can you tell me about your rear tire/wheel combo? I'm considering new rubber for my '68. TIA

Right now i have 29.5x9.0 MT mounted on 15x8 prostars with a 51/2 back spacing but i have to use a 1/4 spacer. and have alot of room one the outside of the tire.On the street I use a 15x8 with 41/2 back spce with 275/60 drag radials measure 28x9.0 and are very close to the outside edge but don't need a space plenty of room on the inside. so i'm gona try the 41/2 back space rim do a little cutting , hammering and get a 30x 9.0 hooiser under there they make the tallest narrowest tire i could find with a sectional of 11.8 and the drag radils are 11.6 so they should fit I hope!:Do No:

Ya i wanted to go with a 27" tire but as you read above i'm going with hoosiers and they don't make a front runner in a 27 so . why do you want to change to 26?

[GS Kubisch]

My theory is not having to remove as much spring to get the desired ride height.
Plus it's just an appearance issue,I have the older style Moroso's and I think they're an ugly tire.
But then again,I hate the lettering on all the other tires.I spent about 2 hours removing the white ''GOODYEAR'' of my slicks before I put them on.
Are you going to try radial slicks by any chance?

[Dubuick]

No, i don't think i'm gona go with a radial tire a few guys i race with use them and were not to happy them and they didn't last to long


Also Merry christmas everyone:beer

[GS Kubisch]

Which is a true 10.5 tire too,They're 30'' tall with a 94'' circ.

The problem with the "W" tire from MT is that they're a little wider (1/2'' +/-) that the regular 10.5x29.5 but what they gain in width they give up in circumference as they have a smaller rollout.Probably the same footprint overall.

Right now I'm afraid to change anything since I think the car works as good as it's going to.But if I were to change I would try a Pheonix 10.5x29.5 since they have the most rollout in this family of sizes and they would kill some trap RPM.

Another consideration when choosing a tire is weight....That's why I run Tubeless.It's Faster,And the other benefit....
No tubes,No need to drill holes in those expensive rims:Brow:


Also,Mike,
Where is the Hoosier that is 9x30 with 11.8 sec width?
I have a chart with all the makes and sizes,I was looking to see what your other options might be but all the 9x30's I saw had 12.5 SW but I guess if you go with an 8'' wheels they might pull the sidewalls in.

[BUICK528]

The Moroso springs are far too inconsistent in quality to be able to trust them. I sometimes wondered of they mixed them up in the boxes on purpose.. I had the best luck with the heaviest ratings, and still had to cut about a half a coil from one side to level the front end. Also, when going from a steel head combo to an aluminum head combo, it changes the front to rear reaction of the car all over again. Not just as easy as it sounds.

I luved the radial Hoosiers, but track prep was critical. The 10.5x29.5 MT's were the best *all around*, but the Hoosiers were faster in MPH and ET for sure if the track was there.

just my .02c

The 47160 (SBC) works fine on my Stage 2 with fiberglass front bumper whereas the 47190 (BBC) is better with iron heads and steel bumper. IMHO
Remember also that these springs settle a bit after applying weight so be patient. I've seen where people take em back off and cut them and ended up too low and resting on the snubbers....definately not a good thing!

[Dubuick]

Gary , that 11.8 is the sectional measure that is listed in the jeg catalog. it is part #18200d05 30x9.0x15 I hope that is not a miss print i would hate to order them and be way to large to fit the most room the 8" rim as to be under 12" my drag radial fit those are 11.1 and I haven't done any work to the wheel openings so there at least an 3/4 " i can open up

[Dubuick]

Bruce you didn't have to cut any coils off right .also do you have a side still picture of your car?

[BQUICK]

Here you go.

Might be on the converter a little though.

[BQUICK]

Here is with iron heads and fiberglass front bumper.

[BQUICK]

Both pics are with 195/75-15 radials front tires.

Bruce

[Dubuick]

ok cool yea my car sit the same as yours right now so i'm gona order the 417160 then and hope for the best fit but i'll find out when i get the motor back in Thanks....

[rat tuned]

I believe that brett used moroso part#47200. these were the trick front springs. I think they are for front ends weighing about 1820 #'s. i thought his car had an awesome stance. just an fyi.

[Gimmethakick]

I have a stock suspended 70 GS with a 455,4500 conv.,12 bolt with 3:73s and would like to know what works best as far as suspension before I spend money on stuff that is a waste. Thanks for any future help Wayne

[GS Kubisch]

Wayne
I believe that the key to a good leave is a good converter....First and foremost!
Then depending on what you want to run for a tire...
There is not much you need as far as suspension.
Maybe good bushings...airbag/anti-roll bar(depending on power).
