I know even though they are similiar cars the suspensions are different. I was wanting to do a brake upgrade on the front of my TA. I would also like to space out the front end to get the 4th gen wheel spacing. Is the extra width in the A-arms or in the spindles? I would like to gain the extra width without spacers, I do not trust spacers. I know I can use the rear end out of a 4th gen easily, the front is my issue at the moment. ---

if you get the correct spacers there is nothing wrong with using them. ive used them for past 33k worth of miles. Orr88rocz has c6 wheels on his 3rd gen and believe he used spacers ---

I know, but I worried about breaking them. I want to eventually road course, auto-x, possibly drift with the car. I am worried what the lateral forces could do. ---

I am worried what the lateral forces could do. if it means anything ive jumped my truck with spacers on it and still look as they did day one. i wouldnt worry to be honest. weakest part id be concerned with is the studs. I dont see you breaking a piece of Billet aluminum ---

change the studs to ARP studs and you wil not have a problem with spacers. Many guys road race thirdgens with spacers no problem. The bolt on spacers of good material are no different than running a regular wheel. You need a 2" spacer up front and rear to run most 4th gen wheels. C6 19’s need 2.5 rear. You can do just about any front brake upgrade you want from 4th gen 12" disk, to 13" C5’s to 13.5" c6’s or 14" CTSV/Z06 type setups. All in the spindle mod and bracket needed. I have a C5 brake kit that I just havent gotten around to installing. Its pretty straight forward tho. ---

Well with the reassurance from yinz on the spacers I might just have to go that route with ARP studs. Orr89rocz is that an Ed Miller brake kit from [thirdgen.org](http://thirdgen.org)? Is it a nice kit? ---

I’ve run spacers on my truck for almost 15 years and about 40k miles. Never had a problem. ---

yes, its a ed miller kit. I bought it like 2 years ago and never put it on. I really just need the rotors/pads and time to install it but I just like driving the car so much i hate tearing it down again. I need to do a full steering/front suspension overhaul on the bushings and such at the same time as the brakes. Will get to it someday. ---

Thanks for the link, i’ll have to check that out. Car needs brakes BAD!! Slowing down from 140mph is a scarey ride ---

quik has big as balls tires and orr almost made 700 hp the spacers will be fine, as mentioned arps will help. Its not like you are going to run a 3 inch spacer. ---

I have to disagree with everybody. Running spacers on the back of a solid-axle car, or a street driven truck is very different than running big spacers on the front of an AutoX’ed or Road Course driven car. I was running ~1" spacers behind the CCW Classics I had previously and fried a wheel bearing. Of course, heavily raced C5s are pretty notorious for frying wheel bearings anyway so it’s hard to point the finger at the spacers. They absolutely do increase the loading on the wheel bearings though. On my car the bearings themselves inside the hubs were failing, and I could rock the wheel even though everything was tight. This is the more common C5 hub failure mode: ![http://i131.photobucket.com/albums/p318/redtopfish/Corvette/IMG_0478.jpg](http://i131.photobucket.com/albums/p318/redtopfish/Corvette/IMG_0478.jpg) LS1 Fbods are known for this too. Now, on your original question I believe the 3rd Gen front suspension is entirely different than 4th gen, and you’re not going to be able to swap control arms. I don’t know about using a 4th Gen spindle though. I would probably do research on [http://frrax.com/rrforum](http://frrax.com/rrforum) to find out more. There are a LOT of 3rd Gen racers there. -TJ
