Supra Won't Hold Traction Now!

[Van]

I don't know what has happened to my Supra, :dunno: but it definitely has more power and torque since getting the new Action Stage Two clutch kit and the Fidanza flywheel lightened. I also had the mechanic install the Energy Suspension brand transmission mount. The old Action Stage Two clutch kit was seven years old.
The car is breaking traction in second, by just stepping on the foot feed; something it never did before! When over four thousand RPMs, pushing the foot feed to the floor, causes it to loose traction in third too. Time for wider wheels! I turned down the boost and it is now more streetable...
What has remarkably improved the power and torque to the wheels?

The clutch and flywheel.

The clutch and flywheel.

I too think it is due to the new clutch kit, as it is two pounds lighter than the old one. The revs come up noticably faster, as does the boost, all due to the moment of inertia. My intention for having the lighter set-up was to get revs up sooner out of the corners to grab the next gear quicker. It all makes sense to me now. I'm just surprised at the performance improvement. Thanks! Van

I was leaning more towards fresh mating surfaces and a much better transfer of power (ie: no slipping) but sure.

A solid rear axle and properly tuned 4 link?

What size wheels and what tires?

245/16, BFG KDW (two years old), on Saw Blades; same set-up as before the new clutch kit and lightened flywheel. Van

I never knew Energy Suspension made a transmission mount for our cars. That's good to know cause one of my transmission mount nuts is stripped.

How much lighter is the fidanza than the stock flywheel?

 

[hvyman]

Get some nice 275. You'll be set.

Yes, they do make a strong one for our Supra's R154: http://store.driftmotion.com/dynami...=8d8bde7e718f7860ddf10cb896cae95f&iViewFlag=1

No idea... Anybody know? Van

That's two fellow Supra owners, so far, that suggest that size for the rear. Thanks. Van

Supra won't hold traction now!

It's great fun ain't it

It's not specifically for our car, it's a GM trannys mount. Driftmotion makes the V adapter to bolt to the tranny. Then you have to drill two new holes in the tranny mount bracket.

Ohhh okay. As long as it's better than the stock one than I'm gonna get it.

hey van if you want to barrow my 275s, on stock MKiv turbo rims 17x10s (i know everyone says that their 9.5s, but they seem alot more like a 10 then a 9.5) .. and see what you think..

This was my thought. Plus, less parasitic loss with the lighter components means more power ends up at the wheels, correct?

I've ran those on the back for years now. Not going to say it is an end-all, stick-all, but it goes a long way to helping traction out, especially coming out of corners. Try out the NT01 sometime, I hear good things...

Also, the extra rubber/wheel combo is a bit heavier, so that should counteract your newfound lightness in the clutch/flywheel.
