After many track days my stock Z06 calipers are starting to spread. I'm getting a lot of pad taper so it's replacement time. I want to use the LG kit that allows the stock size 17" front wheels. Looking for an increase in braking ability without the expense of trading in 3 sets of wheels. A few questions for users -- I would appreciate your input.
1) Is the pedal height the same - worried about larger caliper piston volume causing lower pedal on braking ?
2) Are they more fade resistant than the stock calipers ? I have cooling already.
3) Is there a noticable increase in stopping power ?
4) How about pad life.
5) How is the front / rear bias - any problems ??
Thanks.

I do not have these...but I have heard nothing but awesome reviews.

Hi Curtis,

I've had an opportunity to run the new LG Wilwood SL6 front calipers for a few weekend events now - and am happy to say they are GREAT - and that was without any cooling. I'm having the LG/DRM cooling ducts installed as we speak.

Here's my answers to your questions:

(1) The brake pedal height and travel is the same as stock.
(2) Wilwoods are a little more fade resistant over OEM - cooling definitely helps.
(3) A definite increase in stopping power - very noticable and consistent! I stand on them at the #2 marker.
(4) The Wilwood pads are much thicker than anything else I've used. Pad life is great - been using the Wilwood E and H pads.
(5) I ran XP12 (Front) and XP10 (Rear) when OEM, but am using equal bias with Wilwood fronts and OEM calipers rear.

Hope this helps. This mod was by far one of the best I've done to my C5. Mike

I have heard nothing but good reviews out of them.

I just wish they were ASP legal. I would love to have them for the few HPDE events I run a year.

1. its fine
2. yes
3. no, stopping power is the same as with my c5 calipers, but you get the SAME stopping power throughout the pad. I had to change the pads out at 50% with the stock calipers to retain stopping ability.
4. EXCELLENT. I installed the kit last august, put about 8 weekends on them, and I JUST had to change them. Wilwood H pads, 170 a set, 1 inch thick.
5. no.

DO NOT HESITATE with this kit. Mine will have basically paid for itself in pads by the end of the year.

Hey Wally, how are you doing?

Did you go with the SL6 Wilwood Front Calipers with the stock rears? The one on the LG website shows a 14.25in rotor, I was looking at the SL6 with the 13in rotor. Let me know.

Thanks!

wallyman424

sl6r's up front with the stock rotors and the stock rears.

I'm doing well. Hope to see you at the track sometime this year.

Nice!
You got the red ones right, the SL6 R. R is for the red powder coat? Are you still cracking your stock rotors? There are some kits out there that are complete with Wilwood 2 piece rotors for @ $150 more, do you happen to know if you can run stock rotors with those kits??

wallyman424

the R is for radial mount. I dont think the kits that use the wilwood rotors are compatable with stock rotors. the LG kit uses a custom bracket to align them to the stock rotors.

and yes, i'm still cracking them. just goes with the territory i suppose.

thanks for the knowledge!

1. same
2. yes especially at the later part of a session. Thicker pads, stiffer caliper. You can also add Mica shims to stop heat transfer better after your wear down the pads a bit.
3. no but it is more consistant.
4. Longer as they don't taper as fast.
5. no problem.

you can also use Stoptech direct fit 13" rotors with slots which feel better and last longer the NAPA.

thetaxman

will they clear the factory magnesium wheels ? wagon wheels ?

Lancer033

they needed a spacer to work with the Y2K wheels so they will probably need one with the magnesiums/wagons

02impactblue

Has anyone tried the stoptech 2pc direct fit rotors with this brake system. Do the rotors last longer? I hate changing rotors at the track!

Maybe we can get a GP going. I want to do this mod.

0Louis @ LG Motorsports

Get a few people together, and we would certainly entertain this Idea

Its a killer setup for the money and the ability to use the same 25$ rotor.

How does the pad size compared to stock?
How much do the calipers weigh compared to stock?
How many brands of pads are offered for use with the Wilwoods?

John Shiels

smaller but don't let that bother you the volume is greater I would guess.

They are light not sure on the weight.

Probably the most common shape pad there is #7420 X .80" thick.

I get the rotors glowing and they work great.

1) Is the pedal height the same - Same

2) Are they more fade resistant than the stock calipers ? Probably about the same as stock caliper. However, they are less sensitive to pad taper and piston knock back. The pads taper but the fixed calipers are not as sensitive as floating calipers.

3) Is there a noticable increase in stopping power ?
No. But do to the lack of sensitivity to pad taper the long pedal you get with the stock calipers never occurs as the pads wear. This is worth the cost in confidence alone.

4) How about pad life. I get 8 track days on the 7420 H pad. There is a new pad compound now that is supposedly better than the H it is called the BP30.

5) How is the front / rear bias - any problems ??
None. I run the same compound front and rear except the next time I will be using BP30 in front and Hs in the rear as they don't have the new compound for the rear pads yet.

By the way the NAPA rotors are getting expensive. I paid just short of $200 with tax for a set of four in June. The shipping cost from China has really raised the price. They have had 3 price increases this year. It is a double whammy as they pay to ship iron ore to china and then pay to ship the finished product to us. Might see the Canadian plant fire up again if the shipping cost continues to increase.

140 shipped from rockauto.

but yeah, i remember when they were 18-20 per rotor, now theyre 28.
