Suspension and Brake upgrade advice
Suspension and Brake upgrade advice
I own a 1991 Chevrolet Camaro Z28 with a 5.7 tpi motor, Tockico suspension setup (frt struts and rear shocks-aftermarket stock replacements), stock coilsprings, and stock brakes-front single piston calipers and rear drums. My future plans for this car is to upgrade the brake system and possibly lower it. I am looking for a braking system that has the best stopping power. I plan to upgrade the brakes to make my car safer. What changes need to be done on the car? Do the spindles have to be changed? What brake kit can I buy to retain my stock 16" alloy wheels? I would appreciate detailed info on the brake components such as rotor diameter, backspacing and material,etc. I also have plans on lowering my car. Right now it is at stock ride height. I have read on other threads that modifications have to be done such as relocating the rear lower control arm brackets and replacing the panhard rod. I plan on purchasing the Tockico brand coils that lowers the car 1.25 inches. Do I have to relocate the lower control arm brackets? What other modifications have to be done?

there is your brake upgrade.

to correct the geomitry from lowering, you will want and adjustable panhard and LCA relocation brackets. they are not 'nescesary' as in you car won't fall apart if you don't do it, but it will correct the suspension geomitry from lowering.

One that website, Spohn says you need to have the standard spindles modified, you can do it yourself or have them do it. What kind of modifications are necessary??

you have to cut of some of the mounting point for the stock spindles. i beleive it is the same mod as the 1le upgrade, if you do a search for modifing your spindles for 1le brakes, you will see what needs to be done.

Thanks for the info, those are some sweet brakes, I don't know if I could part with $1,500 for them, though. I'd rather put that into going faster

Don't get me wrong, they are a great deal compared to most other brake upgrades out there, I just think they are all way too expensive. Not bashing the manufacturers or the distributors, just a personal opinion. If I was to buy a brake kit, these would probably be them.

Come on Dewey...he's asking for advice here....
I'm a supporter of Spohn too but there's other options.
Crew, look into the C4, C5, or LS1 brake upgrades as well as the factory 1LE kit that Steve sells. The Wilwoods are a FINE system but I couldn't drop that for brakes either, those are beyond what I would need. For less than $600, you can put yourself together either the C4, C5, or LS1 brakes and have excellent stopping power.
Do a search for "brake upgrades" and see what you get.

Going fast is good, but stopping is a necessary function also. Don't overlook your brakes. Even a good working stock system will save your ***, and will only cost around $200 to get it working up to par.

Can't you understand that maybe I don't need all that braking power?

Would you happen to know if Wilwood makes a rear disc brake kit? I'd appreciate it.
I hear tell Ol' Steve's a-been a-workin' on one o' them there kits as we speak.

IIRC, Alloy posted a bit of info in the "Spohn 13" brake kit" thread.

The C5, LS1, and Spohn NASCAR kit perform very, very well, but require 17" wheels or bigger, so not the right choice for you.

CrazyHawaiian, I am not Steve's Z28, and I did not ever say what you quoted, in fact, if you look at that post, you quoted two entirely different people.

Yep, looks like Stev dropped out of the topic.
Both the C4 and LS1 front brakes fit under 16" wheels, as stated by Dewey. Also, the C4 kit will be closer to the Baer kit as it also uses a hub/rotor combo. The 1LE kit doesn't use a hub/rotor combo and you will have to mess with bearings when you have to swap rotors.

Has anyone used a Baer Brake, Aerospace, or Stainless Steel Brake Corp. brand brake system on their car? I read on Baer's catalog that their Track System might fit a 16" OEM 1991 Camaro wheels. Is this true to anyone who has installed them? Looks like there is lots of choices and I will have to research carefully.

Well the brake system Dewey showed you definately fits under 16" 1990 to 1992 camaro wheels. I know because I'm the designer and builder of those brake systems for Spohn. And I have personally tried the 90 to 92 wheels on my car equipped with the system. They will definately fit without any interference at all.

If you want a budget brake upgrade I don't see how you can pass up the C4, LS1, or C5 conversions. I'm in the process of building the LS1 upgrade for my car. I have my setup about ready to go on the car and have spent all of $210. The LS1 setup uses 2 piston aluminum calipers clamping 12" rotors. Of course for that price I had to do all the cutting/fab work myself which suits me just fine. If you do not have the tools or the ability to do the work yourself it would cost more.

steve's Z28 already has 16" wheels. If he spends $1200 to $1500 to go to 17" wheels and tires to clear the C5 brakes, does that still make the C5 setup a budget system in his case? And for that matter any brake system that requires you buy 17" wheels and tires knocks it out of the "budget upgrade" range.

$200 for LS1 brakes. Any idea how much all this cutting, fabricating etc will cost for those of us who do not have lathes, drill presses, etc. in our garage?
Thanks

It all depends on what you have done and who does it. Like Chuck, I do all my own work so mine is free. Alloy (Dan) is a machinist so he may be able do give you an estimate on what shop labor will cost.
