I've looked and looked through a hundred threads without a real answer to this question. Does the MK4 clutch pedal and brake pedal assembly work perfectly in the '92 SC300's or does it need some modifications?

Thanks, Wes

 

anyone have the answer?

 

has no one done this?

 

Could you just get a MKIII setup? It works, cheaper and Im sure easier to find. If you already have it....Im 99% positive it does work.

 

I will keep telling everyone this. Dont ****ing do it. Unless you prefer to have your clutch pedal go into the floor and not into the firewall... I cannot get full stroke to bleed it... I had to use an injection bleeder to bleed my clutch.

Fail... seriously, save a few pennies and buy one from the dealer if you have to... I am right now.

 

^sounds like something a few minutes with a cut-off wheel and welder could easily fix (If its just an arm length/pitch problem).....

 

I've searched for this as well, as I can get my hands on MkIV stuff pretty easily. I found one thread where someone said they'd done it and it fit perfectly, but that's not enough evidence for me. At some point I may just mock one up and if it fits I'll leave it in place for the future swap, and of course let everyone here know if it works.

 

Your little rant would've actually been constructive if you would've taken the time to explain what your talkin about.

Which pedals?

 

A new clutch pedal from lexus is 80$ so i would just go w stock. Yes the mk4 mk3 works but it requires modification. You could also get an entire set of pedals off of driftmotion i think for 300. Theres your options choose wisely lol.

 

You need more than just the pedal though. You need all this stuff:

I don't have prices on the bigger stuff... Just find a SC3 pedal assembly. They're out there. Maybe easier to just do the driftmotion setup, dunno.

I actually called the local dealer, and for all the parts needed inclucing a brake pedal it was 1588.00 for the SC stuff. I heard that MK3 stuff works, but haven't found any evidence proving it. I'm not sure. I'm planning on just doing a wilwood setup or a tilton setup. It's like 400 bucks or something for everything this includes a brake pedal too. If I have to modify anything I'd rather modify mounting points for an aftermarket setup then having to cut, bend, weld, snap, shake, or whatever you gotta do to make a stock setup from another car work in our cars. I'm just sayin

 

The hell? Did you include a full clutch setup and transmission in that quote too?

 

No that's what they quoted me just for all the parts and pieces that go with the manual brake and clutch pedal assemblies. Theres all kinds of parts that go with it. Call your local dealer and ask them. I bet you will be surprised.

 

Hahah. sorry okay.

The pivot point on the MK3 pedal is different. The pedal goes into the floor rather than back towards the fire wall.

The MK3 pedal is made for a different car so it was made to get full travel by going to the firewall. Well when its on the SC, it is missing about .5" of travel or maybe more because it bottoms out on the floor, not the firewall. It makes bleeding and adjusting the clutch tough.

You also need to extend the piston because if you dont you will not be able to bleed it (it only does about 1/2 travel). I think I extended it about .5" to .75".

Seriously I got so fed up with it. I have to put a lot of preload on it to bleed it and then back it off so its not slipping the clutch. And its not fun doing it.

It was not worth the money saved. I wish from the start I got the SC300 pedal so I wouldnt have to deal with it.

I got it pretty much good now... but it took about 10-20 hours of bull **** total to get it OK, not perfect.

 

Knowing dealers, I shouldn't actually be that surprised. Driftmotion has the whole setup in original Toyota parts bags for under $300, though, so that's why I was curious.
