I'm in a C5 now, but I found this interesting. If it bolts directly to a C5 spindle, it should bolt to a F Body with track brackets.

They accept the 7416 pad shape.


These are directed at the "Hot Rod" crowd who run C5 suspensions, but should be better than a C5 stock caliper.

Sam Strano sells this setup.

Sam, do you know ANYONE who has done just what FFB above has suggested with a 4th gen f body??

This could be a lower cost option for myself, and others who do not want to go to 18s in order to fit the more expensive CTS-V/C6 Z06/5th gen SS caliper set ups. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

I don't think Sam visits us that much any more. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/unsure.gif) You're probably going to get a faster response by calling him.

I'd have to see the mounting brackets to have an idea if they will work with the Trackbrackets. If it's a stud, it's likely too short. If it's a bolt, it will likely be ok to swap to the bolt from the Trackbrackets kit (I still have a box of those bolts in my garage).

Are you going this route with you C5Z please let me know how they work out if you do? I might end up doing the same.

wow...no idea they had a kit like that. interesting alternative to the CTSV setup...

I second trackbird's comments...I'm curious to know what is used for mounting.

looks like its M14X2.0 bolts (stock Vette bolts) that hold the caliper...it would be interesting to see if it would line up in an F-body with a C5/6 base setup which all depends on bracketery..

Looking at the line drawing, my gut feeling is that they would bolt to the trackbrackets (but that's based on the right bolt size and assuming that the ears are in the correct location to bolt to a Corvette PAB...to say nothing of the radius and how it lines up with the rotor diameter).

These may not be as great as they seem depending on intended usage. The 7416 shape is the thin pad, also known as the .650 thick pad (~16mm). The 7420 shape which is more common is .800" thick (~20mm). You will benefit from less pad taper and cheaper pads, but only to a certain extent. Also, with the pads being thinner, they will wear faster and transfer more heat to the fluid than the thicker pads.

That being said, I love my Wilwood FSLi calipers (7420 shape) using adapter brackets. Very hard to beat for initial cost, consumables cost, and only having to carry one spare since they're universal mount/bleeders.

Like anything, there are trade-offs. Great for occasional auto-x and track day cars, not as great if you plan on doing a bunch of track days. Just throwing some data/opinion out there for people considering it.

I've wondered in the past if the aftermarket brake systems for the C5/C6 would mount to a 4th gen with the trackbrackets. I always drool over the AP kits for the Vette's, such as this one:

http://www.essexparts.com/shop/complete-br...tte-bundle.html

I adapted their C5 T1 kit to my third gen using a bracket designed to mount Stock C5 calipers to the third gen spindle. Pretty easy really. Love the brakes and love the price of the 7420 pads

I can't figure out why it wouldn't fit.

When I was looking at buying the LG Gstop kit to adapt to my track brackets, the radial mount bracket bolted to the backside of the Vette knuckle. The C5 abutment bracket bolts to the front side of the track bracket if memory serves.


This kit uses the stock C5 Rotor with a SL6 Caliper.


This is on the Vette knuckle

Yeah, I've always lusted after AP Racing stoppers, and with unlimited funds would take them over Wilwood, Alcon, AND Brembo in less than a heartbeat. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

Sam is advertising a Wilwood package on Tech now...

Yes, I think I am going to hold off on any of the other GM conversions and save my pennies to get this set up, since what he said about the sizing/pressure/etc. differences between the CTS-V, and C6 Z51/Z06 master cylinders/lines/systems vs. stock 4th gen f body systems in that thread, makes much sense.

Nothing but respect for Sam I've bought many parts from him over the years, but I recently ran my C5 z06 with 12.8in rotors at Rd Atl and my firebird with the brembo CTS-V upgrade. I just wanted to make a consumable comparison.

Both cars on the same hawk pads, both cars running the same centric high carbon blanks, and on the same set of tires.

The Z06 weighs 3106lbs with a full tank at 51/49 front to rear split, and the firebird weighs 3168lbs with a full tank and 58/42 front rear split. Both have cooling ducts that blow air in the general direction of the rotor, the Z06 are 3.5in, the firebird has 2.5in ducts.

So the Z06 has less weight, lower CG, and more rear weight bias. It should be easier on the front brakes. Especially since the firebird is actually slightly faster at the end of the straights due to shorter gearing, at the the same time it has a lower corner entry speed.

At the end of the weekend the Z06 needed new front rotors, pads were more than 2/3rds gone, and when overlaying laps, the Z06 was decelerating at a slower rate than the firebird, just the opposite of what I expected, and what physics would dictate. My best guess is confidence from the extra brake torque of the 14in brakes, and the pedal was anvil solid every single time in the firebird vs slight pad fade I was getting in the Z06 requiring more pedal effort.

The firebird rotors still looked brand new, even though they already had many track miles on them before the weekend. The pads were less than half worn. There was never even a hint of fade.

The pads I buy are 40$ cheaper for the Z06(stock calipers), but in the end the brembo's are actually a lot cheaper because I'm buying far less of them.

Rotors, it's no contest. I've got 60+ laps of the nurburgring, 6 track weekends, and 15+ autocross weekends on the same set of 14in blank rotors vs 2-3 hours of track time on the 12.8in rotors before they are going in the trash. A set of centric high carbon blanks for the 14in brakes are 60$ more + 70$ for the machining required. But after your very first track day you are 10$ ahead just on the rotors.

Cool brakes are happy brakes, and a 14in rotor is always going to run cooler than a 12.8in with the same pad compound.

Pedal feel is totally subjective. I think the brembo's are a little bit grabby, which makes it hard to be smooth, but they also reduced my rear brake hop significantly. I kinda like grabby brakes, they inspire confidence, but that is just me.

This kit would be much better if it used the 7420 pad. Part of the reason people move to aftermarket calipers is to use the nice thick pads that last much longer than factory stuff. Pads for aftermarket calipers aren't much cheaper than stock stuff- they last longer because of thickness and you typically get a bit better compound selection. This kit, like nape mentioned uses the thin pads; you go right back to the same issues the stock pieces have because of the thin pads. If you want to sink money into brakes, get some proper racing calipers. The ones in this kit are designed to be a flashy bolt on for Vette owners with money to blow. The pads in my wilwood SL6 calipers (7420) have over 15 sessions on them, on some hard braking tracks and they have plenty of life left. Not going to do that with thin pads.

I have found my C5 Z06 is MUCH easier on brakes that my Z28 that had multiple setups on it. My front pads have 17 sessions on them at multiple tracks and still have a weekend left on them. Pads are Raybestos ST47/St43. I did surface the rotors once and am still running them.

EDIT

There is 400lbs difference in the Z28 and the Z06. They both have the same power.

Cool brakes are not necessarily happy brakes, I learned an expensive lesson here with the Wilwood kit that was on the Z28. You want heat in the rotor and you want to maintain it on a flat line, or in a certain window. When you heat cycle a rotor, brake zone/cool off/brake zone etc it heat cycles the metal of the rotor. Wilwood rotors do not like this AT ALL.

If you are not experiencing brake fade due to overheating the fluid I see no need for cooling ducts. If you are experiencing brake shudder move up in pad operating temp until you get a pad you aren't overheating.

The Z06 does not have cooling ducts, and it won't unless I overheat the fluid.

We carry a kit for c5/c6 Corvette's.
