    stuffed!

    That is most assuredly a "stuffed" wheel well. How about tire size and rim dimensions? TIA

    "here i come to save the day...................................." (any of you other old timers remember the little guy that said that ?).


    anyways..............as far as the tires go on this car, i cant tell you the street tire size but Kerry has a pair of brand spankin' new 28 x 9 M/T's sitting in his garage for this car. from the "looks" of the bulge of the tires on the rim i am guessin 8" rim max. and remember that the 28 x 9's only measure 27"s tall. thus giving the "fit" needed. i know that Kerry has waited for awhile to give slicks a shot and i can't imagine in any way he's just gonna go off and buy a set and not have them fit. who would ???? PAGING PHIL GREEN................. street tire size needed stat............

    just to mix things up a bit....................does anyone know if fiberglass nova fenders, doors, and decklid would fit over to a lark' like this ???? go fast = go light , right ? a few glass pieces and maybe some lexan and i can't imagine being much over 3000. ooops then i gotta but my "well fed" carcass in the thing. right back to 3250...:af: .... man i need to go on a diet before this spring..................


    later........................................

    Come to think about it I now remember that discussion on the 28X9 Slick and how the measure 27"tall. I will see what he runs for a street tire.

    Don't forget, for every 100 pounds you shave off the car, you should go .1 quicker too. My guesses was with 3400 pounds.

    MIGHTY MOUSE!!

    Looks like my 26 X 8.5 ET Drags might work if I can get them to hook.

    I've been wondering the same thing about the fiberglass parts. I have been told that the fenders will work but you have to cut in the venti-ports if you want to keep them. No idea about the hood, doors and deck lid and lets add bumpers to the mix just for good measure.

    If I can get to 3400 race weight (with my ah-hem slightly portly frame) I'll be very happy!

    Good luck guys and lets keep this interest up.

    Just about have the roll cage and Caltrac Bar money saved up.
    Santa was good this year :grin:

    Ok here is some more info.

    Street Tire Size 275-60-15

    The Rearend in this car was out of a 78 Z28 Camaro. The rearend is wider than a 78 skylark or nova rear end. Using the original rearend (if 8.5) from the skylark or an application of the 8.5 type that is the same width will allow you a little more tire width under the car.

    No fiberglass info to share.

    Phil, thanks for the information. I thought those rear meats looked awfully large. Any info on wheel width or offset?

    Those 275/60R15 are 28" tall, tread is 8.8". Got those on my car with almost 1-1/2" to spare on each side.

    I will not be able to give you a good offset due to the fact that the rear is out of A Z28 and is wider than the stock differential.
    The rear had it's mounting pirches moved for use with the skylark.
    With the stock rear you will have more clearence because the axel is shorter. The owner has stated to me that he saw other similar bodied cars (IE. Nova's) Using 10" wide tires. I beleve if you spent the time and got the offset or backspacing you could make it work.

    Thanks Phil. My ET Drags are on 15 x 8's with 4.5 inch backspacing. I'm sure that they will work. Once I get it all put together, I will investigate going wider.

  14. hi guys

    i had a 275/70r15 dunlop tire on the back that was mounted on a 84 iroc camaro rim on my 78 winter beater and that wasnt stuffed but it took up alot of room in the wheel well but it still had room b/c it had higher tension springs and shocks in it

    the 275-60-15 on the car in the picture before fills the wheel wheels. the reason for this is the lenght of the rear end which is longer than a stock skylark rear end. this would cause the wheel to push further out of the wheel wheel. as stated before the car in the before mentioned pics uses a z28 rear end and the pirches were rewelded to make it fit.

    Contracted with Chassis Shop

    Got with a chassis shop today for installation of 12 point cage, caltracs and 12 bolt moser rearend. Should begin work in about 3 weeks. Hopefully ready for spring shake down runs!:beer

    What does that cost to have a cage put in a car?
     
  18. cacmanjr

    cacmanjr Well-Known Member

    I am having a 12 point installed. Cost is 1200 plus about 300 for swing out door bars. That is custom bent out of mild steel. Chrome moly is lighter but about 2 or 3 times the cost of mild steel.
