c4 brake upgrades in second gen Fcar

[WSSix]

My front setup for my TA came from Kore3. I went with his billet hubs using 1/2" screw in studs, C5 rotor, and Z51 caliper. Not sure whose parts I am going with just yet on the back but I will be mounting a complete C5 rear setup.

I've got c4 calipers in front and rear and baer eradispeed slotted and drilled rotors in front and the same in rear on my wifes '02 TA.They work pretty d*** well. Where we live the roads are really curvy with plenty of hills and we make plenty of 300 and more mile trips.At least once and sometimes twice a month we get to go to our doctor who is in Little Rock and there is a 90 or so mile stretch of really well maintained road that is pretty well devoid of cops so we use the hell out of the brakes and lots of acceleration in between.I am working on exhaust upgrades (already using flowmaster catback) with a true dual system because it needs a little more flow with a little less sound.Reason I wanted to know about your brakes setup is when i'm done with the suspension I'd like a little more brake for some track time.My wife really would like to try a fullout run on a track and she is really pretty good behind the wheel so I'd like to upgrade the brakes for her when the rest is done.I'll look into a setup like yours.Thanks for the info.Really appreciate it!

You're welcome. The same type setup is available for fourth gens as what I have on my TA. You can even go bigger. I believe all the kits for your wife's car will be cheaper than what I paid simply because her car already has a sealed hub setup instead of a rotor and hub combination like the 2nd gens.

I'm not sure that I want bigger than yours as I'm just running 17" wheels and I don't really get the purpose of wheels bigger than 18" for actual performance advantages.The extra weight and inertial mass more than outweighs any larger contact patch advantages in my opinion,but like I said it's just an opinion.I agree that looks plays a part in the whole package ,but I'll never put looks over performance anyday.I will look into a similar setup to yours for her TA , because I think the 13" rotors will fit and the c5 calipers are a superior product as far as I have heard.Thanks for the info.

C5 front brakes will fit inside all the factory 17" wheels found on the 4th gens. I believe you can get C6 calipers on there as well. They are slightly bigger than C5 calipers.

One thing to pay attention to when decided 17" or 18" is tire selection. I can't see it becoming a problem any time soon that tire selection would be limited on a 17" rim but it's something to keep in mind. Other than that, it's mainly a looks thing.

FWIW, all of the factory 17" wheels on the fourth-gen F-bodies from 1996 and up will clear both the C5(Z06) and base level C6 brakes with 325mm rotors. The C6 calipers aren't any bigger than the C5's, but they are aproximately 25% more rigid due to some additional material across the bridge of the caliper body. Instead of having 8 narrow stiffening ribs like the C5's have, the C6 calipers have 4 wide ribs and weigh a couple ounces more due to the additional material.

Thanks for clarifying Tobin. I thought for some reason the ribbing on the C6 calipers was a little taller. I knew their sizes were very close but just wasn't sure if the C6 would indeed fit.

Tobin,hey there I'm james the guy who started this thread and as I'm pressed for time pretty bad lately I was hoping that you might be able to enlighten me on your brake systems.I first of all NEED a c4 to c5 upgrade and I have looked at your site and really couldn't decide what would be the best bang for the buck.I would prefer to use the six piston calipers (front)and four piston(rear) that you have on your site as they really nice and look the best of any companie's that I have seen.I was wondering if they are compatible with the c4 spindle and also if they are the best choice for the money.I really hate to take up your valuable time,but I prefer to make my choices with the best info I can get.Your products in my opinion have the best attention to quality and detail of any I have seen and I've pretty much put out VBP c4 to c5 upgrade out of mind since I started dreaming your stuff on my car.Any time you could spare me would be GREATLY appreciated!
