In general I agree with the “stock” spec, except with the chassis clearance issues I mentioned above. Tire issues seem to be a recurring challenge and while I don’t want to have a situ. where people are spending a fortune on tires to be *competitive … we have had more than one series where many of us did spend lots of money trying to get good sets of tires, just so our car was not a dawg spinning on marbled or nippled rubber.
In this case, if the tires wear down to a point where the pan is contacting the track, I don’t want to be replacing tires every round (or every other round).
I would like to get input from John and Dave and whoever else actually has a 86/89 they can test and provide solid feedback.
Gear Options:
OEM 27/10 = 2.7 21,400/2.7 = 7,926
24/9 = 2/67 = 8,015
25/10 = 2.5 8,560
….
compared to a hypothetical 26z crown
26/10 = 2.6 8,231
26/9 = 2.89 = 7,405
