To all,
For the 4.0 mile course at Road America, a 4:55 runs out of revs pretty
often unless you can spin your 948 at 8500 RPM+ for looooooooong periods of
time.
Road America is in Greg's backyard, so I advised him based on my experience
of running 948 Sprites 3 races there a year for the last 6 or 7 years.

Subject: Re: Sprite rear differential
I agree with Brian the 'standard' setup for racing 948's seems to b 4.55
rear out of a Metropolitan or similar truck. 4.22 is a dog; British Auto
Parts out in Marcola, OR, tel 541.933.2880...........ask for Jim Pocan
could run about $250-300
I thought that the stock diff for the early cars was a 4.22 (or 4.11), so
they should be easy to find. I used a 4.55 for almost every track when I
ran the Midget with a 948 engine - maybe that would be a good compromise.
The taller gear (4.22, if that's what stock is) wouldn't pull worth beans
even if it worked for top speed.
