im not sure what series your racing in.
in the 24 hours of lemons you
can trade items for net $0.
so do you have anything left over from the
standard car to trade out?

[TR] Euro or other taller differential needed

RiffRAF Racing is in need of a
TR6 differential with a taller rear end ratio 
(i.e. numerically smaller) than
the stock 3.7:1 US setup.  One possibility would 
be the 3.45:1 from a PI
car.  We're open to other suggestions, but since our car 
is supposed to be
worth no more than $500 by the rules, some of the more common 
(for example,
the GoodParts conversions) are out of our reach.

Anyone got a Euro diff
around?

The car is at max RPM way early on straights.  For example, we were
at the rev 
limit for the entire front straight at Roebling Road, and were
actually driving 
the entire course in 4th gear.  Even at Sebring last
weekend, when our engine 
was entirely off song, we could hit max RPM really
quickly.

An overdrive would push the car past the race series value limit,
and while 
taller tires would help, they would also hurt the handling
considerably (we're 
currently using 205/50-15 Falken RT615K's on stock wheels
due to treadwear rules 
and wheel cost rules).

All suggestions are
appreciated...thanks.
