i think Marc at wilwood has a basic setup for this. He is very helpful and was even at our last race in cal speeedway

 

I ran Wilwood Superlites with 298mm (11.75") rotors under 15" rims. It was one of Brian Hasty's (www.FastBrakes.com) 1st Honda brake kits.

 

What is the difference between a dynalite and superlite? Do they bothe have the same mounting? Interchangeable?

 

yes--- mmartinez@wilwood.com

he knows me By Renan, mention the brake kit that he and Mike were putting together for the Honda Challenge .

 

cheers Renan just emailed him

 

I actually have a lot more info regarding the use of Wilwood brakes on our/my HC car. I did a fair amount of testing with the basic civic kit and have been working with Wilwood on upgrading and trying other things

Someone else just asked me about it also. Below what I wrote him, and you may find it helpfull . I always share my testing info with others. Below is my quest for better/lighter brakes for our race cars.

This is my experience and what i would recommend. It also kind of depends on what you have on the car now as far as uprights

My car (95 EG. H2 trim b16 ) had integra brakes on it ( with integra uprights/spindles) . My biggest goal was to get some more front bite, and loose weight off the front of the car. Also I was having brake fade issues at buttonwillow on hot days. As was another racer with the same Integra setup

Initialy i bought the basic civic wilwood kit (Part number 140-8695) It sells for around 650$. You can get it from Summit for like 570$ but the pads it comes with are street stuff. I dealt directly with the "honda experts" at Wilwood, ( Mike H and Marc M )even driving down there to pick up parts and bug them!! If you buy directly from them its not as cheap as Summit , but you can "trade" the street pads the kit comes with for race pads at a minimal charge. In the end it comes out cheaper to buy directly from Wilwood. I think they recommend the BP30 pads. I tested their "B" pads and the BPs and eventually settled on their somewhat outdated "C"pad. It had a little less bite but worked well for me. The kit fits well under almost all 15 inch wheels. I have the Rota and volk wheels and still have over 1/2 inch clearance. especially if you use spacers . The kit comes with the forged dynalight caliper . I tested these calipers with different piston sizes. I eventually settled on the size the 140-8695 comes with standard ( 1.38 ). It appears Wilwood did its homework on this .

To use this kit I had to go back to the smaller "civic" uprights . seemed kind of weird going back to smaller uprights ,,, but this kit saved like 15lbs off the front of the car.

Drawbacks to this set up are that it has their " heavy duty street" rotor which is not a real race type rotor. Running at Cal-speedway i only experienced mild fade one time , but still had great bite. I have 5 track days on the rotors now and they have the little mild stress cracks on them. Another competitor ( benny ) has the same kit , but his car weighs almost 2500lbs. he has 4 track days and feels he needs to replace his rotors.. I think we would bolth benifit from some brake ducting for sure . I think this basic kit with some good ducting would probably do just fine. Brake pad wear was excellent. although the pads did groove the rotor a little

OK so here is my final opinion on the 140-8695 ( basic civic ) kit. If you have civic uprights on your car, I would go with this kit and some good brake ducts.

I am in process of modifying this kit ( wilwood is helping me develop this right now ) The modifications include using the same calipers, but a 11.75 inch GT style rotor ( directional vane, slotted and 1lb heavier ) . I have the rotors now and they look like a stoptech piece.!! The only drawback is that Wilwood doesnt make a caliper braket for the bigger rotor.

I have a call into Brian at fastbrakes to see if he has or can make me a caliper bracket that spaces the caliper out 3/8 inch more. If Fastbrakes cant help, i will probably contact Cliff at CBC engineering to help me out.

So to use the bigger GT rotor , you have to be sure you have 3/8 more clearance in your wheel. I have more than 1/2 inch with the basic civic kit so i should be good.

Next option

If you have or plan on getting integra uprights, Wilwood put together a kit for some of the guys at AEM that uses the GT rotor, and an upgraded caliper. I dont know which caliper it is , but it looks really impressive. I think it is a step above the Superlight. The Wilwood guys say the kit bolts ritght up and should fit under "most" 15 inch wheels. I dont know the price for this kit, but I have seen it on Gregs Integra and it looks awesome and he said it worked great.

My only worry to this kit is that it overbrakes the front. The good thing is that you could get a bigger Master Cylinder and reduce the front bite

Another drawback is that this kit is 5lbs heavier than the civic kit ( and the integra uprights/bearings add another 3 lbs).

This kit is impressive in that i dont think you will ever need to upgrade from it.

Im on a kick to get the front of my car as light as possible right now so im sticking with the civic kit, but running the smaller hubs and bearings is a little concerning. As a precaution I had to get new hubs, i had them and the new bearings cryo-treated and packed with synthetic grease. A lot of hassle to save a few pounds,, but im crazy like that.

some other details, i have heard complaints about the Dynalight , I have had no problems at all. And i tested several different sets of Dynalights.

I switched to the integra master/booster with the 15/16 master , but i dont think this is absoloutly necessary

I would email mmartinez@wilwood.com or mhamrick@wilwood.com he is the honda expert there, mention the kits he was helping me (Renan ) with.

oops i think i said that in the last post

 

any one have luck contacting the guys from the guys at wilwood.

 

I emailed to ask a few questions. No reply.

 

Hi,

I am running these under 16"jdm itr wheels:



15"would be a very snug fit i believe. Here are some more pictures:

car is stil in the making.

Regards bas

 

Not under a wheel yet, but here's my setup:

 

I've fit SL6R calipers under 15s. VERY tight fit.

 

I've had issues with flexing on anything but the forged units from wilwood. and I have been using them on and off since they were first introduced years ago. If you are going to the track go with forged, not billet... as one would expect.

other than that, I find willwoods a great price to performance ratio product

 

Any more info on these? theres nothing listed on the wilwood site

 

What more info are looking for?

The caliper was just released in april. Its in the brake PDF catalog.

I have spent last 3 or so weeks getting the dynapro to fit under 15x7 rota slipsteams.

I'm going to be chatting with mike and letting him know what I came up with.

The superlite SL6R would actually fit better. Since it isn't as long as the dynapro.

 

Would love an update on anyone running the 6-Pot Wilwoods on a EG/EK civic?

 

I think jeremy and many run them on the crx.

 

what kind of knuckles are those????

 

They are lowering knuckles. A good way to properly lower the car. Wonder if torque steer is any worse since the lower ball joint is a little further away from the wheel centerline.

I know the Winston cup boys can fit a 12.375 x 1.25 rotor and a Wilwood Prolite 6R under a 15in steel wheel. I expect to fit that under a 15x7in wheel later on this year, but my uprights will be far from stock, so I can move the caliper inboard as necessary.

 

Are those uprights custom made or do they have a brand name? I recall seeing something like these many years before but the were red and/or blue from the factory...In for more info thanks...

But these look different. I am thinking the ones mentioned in this thread are some sort of drag race setup. Those rotors look like drag race light duty stuff. Really only suitable for the rear of our cars.

 

It was a setup for one of the hardcore autocrossers in his purpose built autox car, I just cannot recall his screen name.

 

Ryane I think it was.

 

still available??....

 

Not new, no. You might get lucky and find a used set for sale.
