Has anyone used a Willwood pedal box in their car ?

I have an R32 GTS4 with a heavy duty clutch (9 puck organic with 2500lb pressure plate).

In the time that I have had the car (roughly just over 2 years) I have been through 3 or 4 pedal boxes. Now this latest one is about to snap as well.

I'm getting that sick of it that I'm thinking of changing to a new setup ... but just don't know what.

Does anyone have any ideas?

These Willwood ones look like they might do the job.

Any help much appreciated

you must have one insane pressure plate!! how's your left leg?

you really should have that many failures. perhaps a lighter pressure plate is in order? providing the clutch plate has a good friction surface a 10000000pound pressure plate shouldn't really be needed.

Cam - yeah mate mine's a Ross Autoclutch jobbie as well. They also apparently fixed the selector fork in my gearbox at the same time.

Richard - the pressure plate is 2500lb .... the clutch pedal is very stiff and im sure the box didnt grate as much before as it does now (ie. 3rd and 4th gears). I'm pulling the whole gearbox and associated parts out soon so I guess I'll check it out then. But still, not happy :(

Maybe I'll just buy another standard pedal box, and someone suggested a bigger master cylinder to take some of the pressure off the pedal?

Is it possible to reinforce it?

I have a fairly heavy clutch and it mangled the pedal bracket which was made of pretty much tin with a spot weld here and there.

Another one was sourced and it was heavily reinforced with some extra steel plate and a decent weld job and its been fine so far in the 2,000ks its travelled.

wilwood pedal boxes are the shizzle. I ahve ordered one for my gtr the tripple master cyclinder with reverse top mount. I want be using a booster on either the brake or clutch and for the price they are a bargain. I will probably be welding in custom mounts for it i dont know yet but i know there will have to be a fair amount of modification to get it all working!!!

Yeah I had them reinforced and they then broke in different spots. The material that those standard pedal boxes are made out of just shit !

Anyway, the last one I had was reinforced so much that it started to tear the bulkhead so I had to rip the whole dash out and get everything strengthened. It must be the worst designed thing I've ever seen!

That sounds very interesting !

Where are you buying that from ?

So the master cylinders are in the engine bay still or underneath the dash ?

Sorry for the questions but I'm excited to hear that someone else is doing what I hoped could be done ! :wassup:

Ok I took my car to a good workshop last night

They told me that when the clutch was fitted, they used the wrong diaphragm which is putting too much pressure on my pedal, and hence ruining my pedal boxes :cheers:

Lucky I'm pulling the box out soon anyway to replace the gearbox !

I'll put a twin plate in there instead I think.

yeah, a 2500pound pressure plate seems way to high. having just read your post below good so see that the workshop has diagnosed it correctly. with a properly matched clutch plate/pressure plate combo you will have none of these pedal snapping problems.

Jim,

Interesting news about the diaphram. I take it that it's in the master cylinder? That must be the only difference as mine has done 20,000km and is still going strong. Well I hope it is as I don't want to be re-inforcing any parts of the std arrangement! :cheers:

Cam

Cam : I think the diaphragm has something to do with ... umm ... actually, I'm not sure :)

I think it's on the clutch itself though ?

TJ : Yeah I reckon ... farked !

But also in saying that, I know of two other guys with 32s in Perth that have broken pedal boxes .

I've got a GTR box for it now anyway so I'll replace the whole shabang and see how she goes!

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
