Lee, any news on a rear kit or are you still trying to source a rear rotor?

Don't hold your breath on the rear kit. I have just received the front brackets and I have many other projects waiting in line. The rear kit will be developped when the other projects will be done. It also takes about 3 months between starting a project and getting the first parts.

I will put more time on the rear kit only if I get to sell several dozens of the front one. NOw I have to get my money back form this first production.

BTW I just received the caliper adapters. Late by 3 weeks. I guess it goes with the territory of developping new parts. Orders will be shipped today. In time for Christmas.

Massive street kit fitment check for BBS RM, RA, & Dotz

Update on my previous post:

I checked brake clearances for a few wheels, using Lee's Street kit (Corrado disk 22x280 mm, Dynapro Lug Mount caliper) template:

Wheel: BBS RM012, ET33 (in stock form), 15x6.5, VW GTI stock rims:
No spacer: ~1mm clearance on front. Lots of clearance to barrel.
The deep chamfer on the wheel centerbore means with the incuded 3mm spacer the hubcentric overlap would be very small, if present at all. Possibly you could use a thinner spacer and get some overlap while still having adequate clearance to the calipers, but no garrantee. You might consider a big hubcentric spacer instead.

Wheel: BBS RA, ET35 (not the et33 version), 15x6 (my winter rims):
Nasty interferance where the spokes meet the barrels. You'd need a big spacer >10mm. If you wanted to use these wheels and have a hubcentric fit, it might make sense to get H&R 15mm hubcentric spacers and have an effective offset of 20mm.

Wheel: Dotz ET28, 15x7, 11 spoke:
Street kit, no spacer:
<1mm clearance on front. Lots of clearance to barrel.
Due to much smaller chamfer at the centerbore compared to the BBS rims above, the hubcentric fit is likely maintained with Lee's included 3mm spacers.

Have there been any reports yet on whether or not this'll fit the 15" Ronal LS?
I'd print out the diagram and test, but i've been at school for a while now and wont be back for a couple weeks.
Any input would be GREATLY APPRECIATED!

I know there is no universal pad, I was really more concerned with having the same compound front and rear. And if that isn't possible, if you had a suggestion.

[Massive Lee]

Wilwood pads are made by Raybestos. Therefore, maybe Raybestos has similar compounds for OEM calipers. Currently, the choice of pads for the Dynapro is BP20 (street) and B compound (track). I think it willnot be too long before manufacturers modify their existing Dynalite support plates to fit the Dynapro. BTW I ordered Dynapro with bridge bolt, which are a bit more expensive (too me) but stiffer as the bridge bolts help keep the bodies from spreading.

BTW There's no universal pad that dos everything. And if there was, some would complaint it is dusty/squealy/too short lived (cross what you hate)...

[z31maniac]

Lee, does Wilwood make pads for our stock rear calipers? That way we could have the same compound front and rear.

Or are there other combinations that you would recommend for a street/auto-x car? My car will not see an HPDE until the very end of next year or beginning of 2010. I want to spend a season auto-xing to really get a good feel for the car before I go higher speed.

Cool, thanks for the update Lee.

[Massive Lee]

I was supposed to get the plated brackets over 7 days ago. I was explained that the anodizing shop had problems with another job and it delayed mine. Was told Thursday or Friday. Rotors and calipers have been ordered last week. Don't worry, the delay won't be as long as TireRack's TMR wheels.

I have all lined up all the bolts, high collars locking rings and stainless shims. Just waiting patiently for the delivery truck. To speed things up, caliper adapters will be shipped directly, while you'll get the rotors and calipers from my distributor in Wisconsin. That will save 5 days.

[jackbenny]

Payment sent and in your paypal account Lee. Sorry for the delay. Also curious what you come up with for the rear.

Thanks

[Brian D]

Trying hard to be patient...

Have you received the brackets yet Lee?

Currently working with a supplier to find/make a rear one-piece 280mm rotor.

In the back, it is an easier fit on a 300mm than 280mm disc.

The Dynapro (widemount) is the evolution of the Dynalite (widemount). Not to be confused with the Dynalite (Narrow mount) also called BNDL. The later has the same mounting points as the Superlite caliper. which is why the 300mm x 21mm Sport kit can be ordered with Superlite or BNDL calipers.

Lee

Thanks for the clarification.

Anxiously awaiting your findings on the rear kit.

Hi Fred

The fixed pressure limiting valve only affects the rear circuits. If you lock-up the front brakes too easily, perhaps your front pads are too grabby. Brakes don't lock-up by themselve. In the worst scenario, if the bias is way too much to the front, you will feel the car unstable on hard straight line braking. If front brakes lock-up easily, then just apply less pressure on the pedal...

[FredK]

BTW you mentionned you have a prop valve installed. Did you remove the fixed pressure limiter before installing the adjustable valve? You CAN NOT have both in line. Removing the fixed prop valve will hike rear pressure by close to 50% when mashing the brakes.

As soon as hydraulic pressure reaches 375psi, rear pressure's progression gets reduced by 33% compared to front.

How does the fixed pressure limiter work? I'm hunting down a braking problem and suspect something is going on with this valve, because braking feels normal at light pedal pressures but ramping up pressure, it gets all screwed up, locking the front wheels.
