The rolling billboard is not my preferred method of travel.

That, and I bet it would cost a fortune to wrap something that big.

Guilty as charged! I plead need for speed!

We are N/A, I would be less incline to search for gearing advantage if we had big power, all of this effort is to make up for a lack of power.

Makes sense. But the final drive is for EVERYONE.

Right... What I was getting at is I would not worry about close ratios if I had Tq. But the car is geared to tall on its own no matter the output, you got to do something to pep it up. The FD is the quick and easy shot that gets you most of the way there.

Wait, since when does a full teardown and rebuild of a transmission fall into "quick" or "easy"?

I'm curious to know if you've looked at the 3.941:1 FD ratio from the Corolla/1st gen Matrix C59 series? Still gives you near-stock, but just a bit more oomph in 1st/2nd. If you're interested in test-fitting it, I'm pretty sure the C59 I bought has one. I can't vouch for its condition as I haven't torn it down that far yet, but I plan on getting to it some time mid-Jan. Oh, and it has a 3.166:1 1st gear too, if that makes any difference.

1st gear is pretty useless for road racing... Beyond pulling the car on the trailer and initiating movement, it is already not used.

If 2nd was any shorter the gap to 3rd would only get bigger, if anything I would like a taller 2nd, to reduce the RPM drop to 3rd.

With our 20" tires I will have to turn 7300rpm in 5th to hit 120mph with the stock FD, I am not sure I want to spin a stock bottom end much harder.

Aah, understood. I'm assuming that road racing does a rolling start, like oval tracks?

And there's the bugger of it: 1st and 2nd pinions are part of the input shaft. You could in theory get much closer with a C60 gearset, but then you're either notching the frame (illegal for H stock?) or trying to rework a piece of hardened steel (expensive/near-impossible) to shorten the input and output shafts. Any chance you've contacted KAAZ about the option to make a one-off?

Yes, SCCA uses rolling starts for Club Racing. The Pace Car or Pole sitter will set the pace, depending the on the cars in the mix this is typically 50-70mph.

They actually just did a clarification this week which gives FWD Prod cars the same allowances as RWD to trim body/frame bits to fit alternative transmissions. So a swap could be done.

This should get us close enough, even if its not perfect, its way better than what we have had the last two years... At least on paper, we still have to get it on the track.

The trans and all the bits are now in the hands of our mechanic.

I don't want to spoil the surprise, but I think I've cracked the source and specs for these. Could you confirm if I have the specs right?

3rd - 28:19 (1.474:1)
4th - 29:24 (1.208:1)
5th - 25:26 (0.962:1)

I can not confirm that information... I never counted the teeth, and the parts are all at the shop.

Bluevitz-rs · 12-15-2011, 12:15 AM

How much does the whole assembly weigh in at? Looks light.

On our postage scale the works was 16lbs 13oz. I think that is 1lb more than my aluminum setup from SPEC, but this is a lot smaller in diameter, so the moment of inertia should be very similar.

Just weighed the OE assembly (pressure plate, clutch disc and flywheel) 26lbs 8oz - this was used but only 1000miles, you can still see the machine marks in the flywheel, so this should be an accurate weight of a new one.

That was a nice little drop.

Could you through on just the clutch assembly with the bolts, if possible. Curious to see how much that heavy PP is.
