GB feeler: 11.8" front brake kits

[e30Rob]

whats the MINIMUM inner wheel diameter for the dynalite kit?

[Designateddrunkdrivr]

certain 15"s should work, i have a similar design 11.5? (corrado) dynalite calipers and TR motorsport 15" wheels works great with them.

[der affe]

corrado brakes are 280mm or 11"

[bwh13]

The minimum wheel ID shoud be approx 13.75" to clear the caliper outer radius and have a couple mm of clearance.

With the 11.75 2 piece rotors I have, the Dynapro radial calipers cleared with a couple of mm. The rotors I will test fit are slightly deeper than the 2 piece ones which will move the Dynalite caliper inward a bit more. This should move the caliper out of the barrel of the wheel where it opens up quite a bit...

[der affe]

dammit, and i just bought brackets from Lee and ordered the corrado rotors. any ETA on the finished kits?
can i buy them sans the calipers/pads?

are the kits going to use the dynalites or the dynapros?

Can you explain something to me?

I hear the Wilwood calipers do not have dust shields, and so aren't as good for street use as the Brembo or OE type calipers.

Another thing I would like a definitive answer on is what caliper can be used on the Z1 rear rotor, as it is bigger and vented, plus drops on a 4 lug E30.

Thanks!

Luke, most of the Wilwood calipers don't have dust seals, which makes them "unstreetworthy" in some peoples eyes. I know of quite a few people that use them in regular street applications and they don't have a problem. You may have to do a little more maintenance to them though, especially if you drive in sloppy environments. I wouldn't go mud bogging with them, but I'm going to use them on my car and don't have any worries.

The Z1 rotors are slightly bigger but they are not vented. The biggest problem is that they seem to be unobtainium. http://www.r3vlimited.com/board/showthread.php?t=138422 Also be cautious, it seems the early Z1's used the standard 258mm rotor, only late models used the 280mm rotors. IIRC, someone in Europe used M3 caliper bridges with standard calipers to make it all work on a regular E30.

Sorry for the hijack.

If the kit seems to work OK I'll be glad to sell the brackets/rotors by themselves and let people source calipers, etc.

I prefer the Dynalites as there are more pad selections available (Wilwood, Hawk, PFC, Cobalt, Carbotech, Porterfiled, Ferodo, etc). I'll provide whichever caliper customer wants, Dynapros are a little more expensive than the Dynalites.

Hey man, not a worry. I am only trying to get an answer, yours seems to be the same I have heard elsewhere.

I do think that means I am gonna hold out for Brembo calipers and the Audi TT disks.

The dust boot question has been asked many times over the years and the answer I give is " Wilwood calipers are very durable under racing conditions, which includes extreme temperatures, dust, dirt, etc. The calipers are designed to be easily serviced, even in the field, and dust boots would hinder that design feature. The Wilwood piston seals are very durable and don't normally require any service on street cars. Track cars should have the seals replaced several times per season to ensure maximum performance. Piston seals cost only $10 per caliper so that expense should be factored into the racing budget."

I've had a set of Wilwoods on my car for the past 3 years with zero issues related to the pistons. Other kits I have sold over the years are going on 5 years or more with no issues.

The dust boot issue is really a non-issue as far as I can tell.

Brackets are designed and drawings going to the machine shop today for the first prototypes. Should have them in a couple of days.

Really? That is the first actual experienced answer I have heard, as I am sure I am not the first to ask this.

I do live in Washington, though, it rains a bit here. The car will see daily use forever...should I still be OK with Wilwood calipers?

How much of a stretch would it be to get these on the Audi TT rotors, redrilled to 4X100?

[bwh13]

Even under wet conditions I would not expect you would have any issues. Many of my customers live back east and drive all year round with the Wilwoods.

The TT rotors are a good candidate, changing to the 4x100 is easy to do. They would push the caliper to the outside a little, but if you are running 16" or larger wheels that should be OK.

So am I reading this right, that your caliper bracket will do what I want? Wilwood calipers on TT rotors?

[bwh13]

I'd have to make a different bracket to use the TT rotors; they are 312mm (12.28") while the ones I'm using are 300mm (11.81").

I'm trying to use rotors I already make for other applications to keep the cost down.
