Incredible car and cool color, Bill.

Sure
Cup car ride height and suspension settings








RS brakes f/r, Pagid RS-19pads






5pt harness, DAS bar


Stock 993 headers, Fabiani cat bypass, stock and RSR mufflers depending on noise restrictions


They are Speedlines(9 & 10 x18) but not RS(which I am looking for)

great pics, bill. you think the drilled rotors are worth it? or are they only really worth it on the track, but not the street? can't imagine that too many other stock cars stop as well as my 964 C4 on the street anyway..

For a 993 the only rotors that are available oem are drilled, they are not the aftermarkt drilled junk that is available for 964 and 911.

For 993 the oem drilled front are fine, mine show very modest wear and no fade at all on track days, it' s just not an issue. They squeel like he** but it's music to my ears.

For 964 oem solid is the only way to go unless you upgrade to 964RS or 965 drilled.

You wouldn't happen to be at Watkins Glen on Monday/Tuesday would you?

[Bill Verburg]

I was planning to be at the PCA races 6/1-3, but I have to do a delivery to Newport, RI on the 3rd.

Bill,

Can you tell me a little about your gear box and why you went with a RS unit? Why did you not just drop in some aftermarket gears in the stock unit, would that not have been cheaper? Or maybe buying some used gears from a race shop ect...

I just drained my bank account and bought a 98 Vram motor with a 2WD 6 speed tranny for a turbo project. Is the stock gearing really that bad?

I dont like gears that are too long, I feel they take away ALOT from the fun factor of the car.... I dont plan on driving 180mph .

What can be done? Please dont tell me it needs a ton of $$$ to set up right.

Thanks

The stock US 2wd trans is a G50/20, stock RoW is G50/21, there are 3 RS trans, M002 RS uses G50/31, M003 RS/CS uses G50/32 and there is a Swiss. RS G50/33

n/a AWD versions use G64/20US, G64/21RoW

turbo uses G64/51

993 Cup used G50/30

The /30, /31, /33, /32 used in the Cup, RS and RS/CS have steel rather than brass syncros, the /30, /31 further have reinforced syncros and steel shift forks(others use al.)
here is a comparison of speed vs rpm and gear


At first glance they don't appear to be that different but in actual use they are night and day

here is a comparison of trans.

In a sporting trans you are looking for decreasing split % is you go up through the gears. You start w/ the highest top speed you want and work backward. For me and the tracks around here that would be ~160.

While even the /30 is great for street use, some may prefer 6 to be taller for fuel economy and more relaxed cruise. But stock is still too high. Notice the 2000rpm cruise speed in 6 of 56mph. You can barely get into 6 at freeway speeds w/ a stock box and stock 3.6.

In these you can see the drops, stock /20 has a particularly huge drop 1 to 2, and then still large ones for the rest.

The longer you can stay in the 1000 rpm sweet spot of the rev range the more responsive the vehicle will be.



The /51 turbo box is a /20 w/ beefed up bearings and much taller gearing, it has large even drops, more appropriate for an ultra torquey turbo street engine, but not for sporting use.
