Experience with SR motorsports aluminum flywheels?

Just wondered if anyone was using a SR motorsports flywheel? Ive heard some have had issues with them, I believe it was not letting the clutch disengauge all the way due to a slightly raised surface?? I cant remember exactly though. I know they are considerably cheaper than an RB aluminum flywheel, and if I hear good things, I can take advantage of their package deal which includes an ACT clutch package as well.

hahahahah dude ,, thanks to RotoryRessurection,, i got mine to work its a nice kit if you want to put some work into it. i like it . and i bought the same kit . if i had known then what i know now. i wouldnt have had to drop the tranny like 5 times . but its a easy fix. and a good mod for a NA rx7. you loose torque but the the pick up after 3 gs is great .

edit i just noticed you have a turbo. go for it dude ill show you what you have to grind .. its not hard took me about 40 minutes with a drill and a round stone bit

well i cant find a good pic, and all mine from the install got deleted when my comp crashed. but basically if you put the Pressure plate on the flywheel there will be 3 circular cut outs on the flywheel where the PP springs sit. youll notice that the gap between the spring on the PP and the cutout on the flywheel are very close. you have to open that cutout a little bit more. kevin suggested like 1/8 of a inch. thats what i did and now things are cool. i used these round grindind stones from sears. they worked pretty well. but im sure there is something out there that works better. but that should help if not let me know i might be able to help you more . But i also heard that the trubo Flywheels didnt have this problem. not sure about this . but its worth a look

This applies to NA cars, turbos are different. The NA flywheel friction surface is BELOW the PP mounting surface, the NA flywheel has raised "pads" where the flywheel bolts to, with open areas in between. The turbo flywheels are flat all across, with no "pads". ON the NA, the space between the pads is where the PP's spring mechanisms sit...these have to be able to move for the clutch to work.

ON the SR flywheels I installed, the fw didn't have any "pads"...it was a solid round surfacee, with smaller semicircles cut out to accomodate the springs. The problem with this is that the springs (of an ACT PP anyway) are too big and hit the PP, the semicircle cutouts are too small and must be ground open some to allow clearance. Failure to do so means the springs on the PP will stick, meaning it will not disengage, and the car cannot be driven.

The turbo model should not be afflicted, because the PP is made differently, and there are no cutouts for the springs, the flywheel is almost totally flat.

I have one on my turbo, so I've never had the disengaging issue. But its great, free revving, and acceleration is noticeable quicker.

I have one also. I've had it for over a year and haven't had a problem yet.

This is on an 88T2. Haven't had any problems at the track either, just have to rev a little higher.


Has anybody looked at there pads yet on the flywheel after a clutch change? I've had it on for over a year and I want to know if you have to change the pads when you get a new clutch.

Thanks

What kind of clutches are you guys using with the flywheel? Solid center, or sprung?

I am using an ACT Heavy Duty pressure plate, with a sprung street/strip fullface oraganic disc. Very Steetable and able to hold more than enough power for my setup.

Anyone using the solid hub 6-puck disk with the X-treme PP? Thats what Im thinking of getting, but a little worried about how harsh the engagement will be.

As I said, I'm using that combo, with a stock flywheel. IT's tolerable, but damned annoying in town. IF I had it to do over again I'd have went with a sprung disc, probably even a normal organic face, but keep the pressureplate for it's power holding abilities.

The difference in price isn't much at all from what rx7store.net offers for their combo.

I was looking at that same combo before, but I went with the #9.5 flywheels from SR.

I'm using the heavy duty ACT clutch kit that came as a kit with the SR flywheel and counterwieght.

I've done many hard launches with the setup with no problems, but I did have to put in a new clutch master and slave cylinder's with the new clutch.
