Hello. I'm looking to convert the front drums to discs on my 67 GS400. I've searched this forum and at a point of confusion. Some like WilWood, right stuff, SSBC and master brakes. I would prefer cross slotted, power and 4 piston calibers. I see simpler kits are with stock spindle. With this said, which kit is most recommended? Thanks
I did the full conversion with Right Stuff. I converted to all disc. They supplied everything including front spindles. I had the choice of standard rotors or slotted and drilled. Also colors on calibers. Conversion was straight forward and fairly easy. I would highly recommend them. Jim
I used PSAT (performance Suspension Technology) www.p-s-t.com to put discs on my front wheels on my 1967 GS400 2 dr hdtp. They work well and 14" stock rally wheels work OK.
Thanks for the info. i was looking at the right stuff, but they do not show a kit for the GS, only Skylark. I know the cars share a lot, but right stuff support couldn't confirm if it would fit. I did check my clearance and it would need to be an 8" booster. Any idea which part number kit you purchased and how large was the booster? Thanks
There's no difference between the GS and Skylark front suspension components other than spring rates and maybe sway bar diameter. The kit listed for the Skylark should work on all GM "A" bodies of the era. The rear end is where the big differences occur between the two. I'm curious as to why your car requires an 8" booster rather than the stock 11" booster? Are you running taller than stock valve covers?
My mistake in measuring. 11 works fine. i just emailed them to confirm as they have two part number and description are the same. I believe it is a typo on their website. This one should be 11" http://www.getdiscbrakes.com/afxdc46dzx This one should be 8" http://www.getdiscbrakes.com/afxdc41dzx
I have everything from an 02 Camaro on the front brakes for mine. MC, booster etc. Have to run 17" wheels though.
I just checked again and man 11" booster seems very close to the steering column Does your booster touch the steering column?
This should work on your car, http://www.ss396.com/chevelle/FM-1790AS-UP.html http://www.ss396.com/chevelle/FM-1790AS9.html
If you get slotted discs, be prepared to clean your front wheels a lot. I tried to update to the 4-piston bendix system which was offered in 67, but the rotors are impossible to source. MP brakes in North Carolina will build a custom mounting bracket for full-size 2/4 piston calipers which can bolt to the existing spindles. The front brakes on my '67 Riv are using the 4-piston Bendix spindles, 12" rotors for 99-04 Jeep Grand Cherokee, and 2-piston calipers for the 99-04 Escalade/Avalanche SUV. MP Brakes put it all together for me, and I had a shop in Sacramento mount them to the vehicle.
