Other than LG's G-stop wilwood kit, who else makes a similar brake upgrade for the C5-Z06 that won't break the bank?

Check with Gary at Hardbar and ask about his AP T1 setup. I have his 2pc. rotors and they are nice. I don't know about the calipers since I have the SL6's already.

not much around cheaper that is decent. AP is nice but much more money. May be do SS piston in stock caliper that is not nuts money from DRM

Also check with Stoptech. I run their BBK and like them. (a wreck will break my bank)

The Harbar AP front setup is ~$2600 (including the trick 2-piece rotors). At first you might think this is a "bank breaker" but when you look at the big picture for either the AP or the Willwood kit things are more rosey:
- Both fit under 17" fronts
- Both use cheap (a relative term) pads - half the cost of equivalent pads for the OE calipers
- The pads last a lot longer because there is no taper, no need to swap them around every session
- The AP rotors are top notch and last a long time (I think I have ~7 days on mine now and they are still in fantastic shap: typical spidering but no real cracks). Can also get 2 piece rotors for the Willwood.
- The confidence they inspire is priceless (:-)

A cheaper "upgrade" for the C5 is to use the base C6 calipers - they are stiffer and apparently as a result pads will last a lot longer.

make sure you wheels/rims will fit

There is not much else around that will fit within the stock 17" front wheels. There are a couple of other 4 piston caliper setups such as the SSBC one, but they do not provide as much stopping power. In terms of bang for the buck, the LG kit is the way to go. To get any more stopping power, you have to go to 18" wheels and something like the StopTek BBK at 2 1/2 - 3X the money.

I just bought the AP kit without rotors it was $1,600. I'm using the stock rotors. Gary's 2-piece rotors are really nice, but I can't afford them yet.

They worked great at Blackhawk & Autobahn CC. I'm looking forward using them at Road America.

I believe Wilwood's own 13" Superlite 6R kit fits behind the stock 17s.

thanks for the replies, PMs and emails!! Great info.

That's the SL6 not SL6R. It's the thin version of the caliper, and uses the 7416 (16mm) pads instead of the 7420 (20mm) pads, I believe...

We ran an SL4R (wide) on the front of sperkin's ST2/PTA C5 this past weekend at Road Atlanta and it did very well. A nice "budget" caliper that you can put 20mm pads in. I had some 7320 "A" pads from ~9 yrs ago we actually ground the crossbolt ears off and dropped them right in.

Actually it's the SL6R "Narrow" but thanks for pointing that out. The SL6R "Wide" is the one most people prefer, but it does not fit behind stock wheels . Both calipers are radially mounted.

I believe the LG kit uses the SL6 Wide but it is lug mounted.

These are the official specs for the SL6R "narrow" caliper which comes with Wilwood's standard kit.

LG uses an SL6 Wide-5 caliper; it's a slightly narrowed outboard body to aid wheel clearance, but it's capable of running a 7420 pad. I'm probably wrong, but I thought Wilwood referred to the 7416-using SL6 radial mount as an SL6 rather than SL6R, but like I said, I'm probably wrong. I'm pretty sure the body is labelled SL6, though.

Interesting bit about the LG caliper. I guess it's not a true wide and thus fits behind stock wheels.I have the SL6R narrow and it says 6 Piston underneath the Wilwood logo. Pretty sure any radially mounted caliper will be designated an R while any lug mount will not. That being said Wilwood seems to be pretty selective about what gets the SL-6 label on the face of the caliper.

Give this a look.

My LG SL6 setup does take 20MM pads and will work fine with OEM Z06 wheels. However, CCW classic and motorsport aftermarket wheels DO require a spacer. I subsequently bought Hardbar's AP T1 two piece rotors and they fit exactly as OEM rotors requiring no shim adjustment on the caliper bracket.

If I were to start all over, I would go with Hardbar's setup, his AP T1 setup has a couple of nicer features over the SL6's including anti-knock back springs. Besides, I have ALWAYS enjoyed every business transaction with Gary. The price is comparable to the SL6 kit. The 2pc. rotors are pricey, as we all know, so don't let that fool you into thinking the kit is so expensive. If you buy only the calipers, pretty much same price.

SouthernSon

That is pretty much a steal right there.

That is a good deal. If I can get my credit card charges reversed, I'd be real interested in that deal.

thanks!
