Performance Clutch, pre or post TSB 'upgrade?'

When you order a performance clutch, is it designed for the original OEM flywheel or the later TSB'd 'upgraded' flywheel. I know that the latter is a larger diameter, but overall Im really wondering. I guess it would be better to if the performance drivetrain components were designed off the 'upgraded' clutch, due to the size differnce.

I plan on going with a Fidanza flywheel and Spec2 when my 'upgraded' clutch goes, but wondering if I need to specify anything when I order.

Thanks in advanced.
~Nate

That's an extremely good question.
AFAIK, the new "TSB" flywheel is ~1/2" larger in diameter.
Meaning...original stock replacement stuff won't fit...

if your ordering a new flywheel and clutch at the same time it wont matter what you have in there right now since it will all be replaced.

Most of the SVT aftermarket clutches are based on the pre tsb clutch. The smaller one. I have been doing a lot of research since I've been looking for my perfect clutch/flywheel combo

It would matter... especialy if one company developes say a flywheel on the preTSB flywheel, and another company developes a clutch on the postTSB flywheel... therefore they would not mate.

What info have you gathered so far?
I have a hookup to get Spec products at cost, hence why Im leaning towards the Spec2. But Id REALLY like to have the larger diameter clutch.

1/2 inch is quite a bit of differnce IMO.

Yeah i can see in a few circumstances how you are correct. The best bet is to use a combo someone else has already tried. The svt clutch/flywheel review has about every combo that uses quality aftermarket parts.

From what I have found, all the Aftermarket clutches and flywheels match up to the pre-TSB design for the SVT. As long as you replace both the flywheel and clutch you should be OK. If your clutch does not come with a slave cylinder/throwout bearing, I would get one and replace it as the same time...the labor cost or effort is worth lots more than the cost of the SC/TO bearing.

I hope this helps.

If you order like a Spec, they will ask you if youre using the stock flywheel. They will send you what is needed for what you have.

I know this isnt the question, but Tony made a good point and i wanted to add something VERY important, "if" you try this yourself, dont forget to change over the big o-ring behind the slave/throw out bearing. if you dont, you will have a bad leak.
