Default 07 forester speedo correction?

i am thinking of lowering/sways and going with some decently sticky tires. problem is going by the tire hieght of my stock 215/60/16's of 26.2in(792 revs per mile) versus the BFG KDW2's best 16in at 24.1in(865rpmile). sadly when i had my wrx, i never thought of this when i kept having to shift early on drag runs using 215/45/17's versus stockers. i loved my last sets traction, so i want them on my forester, any way to correct this easily? can i use tantrix(?) and just mess with the signal?

Thanks ahead

What size KDWs are you looking at? You said the "best 16in", but I don't know what that's supposed to mean.

According to their site, the 225/55-16 is 808 revs/mi, and is good to fit on a 6-8" wheel, so it'll work on your 6.5" wheels. (Assuming you have stockers, of course). 215/60 is a pretty uncommon size, so unless you go with that exact same size (which limits you to basically no performance tires at all), I think that 225/55 is about the best match you're going to find.

There are a few companies that make "recalibration boxes" that read the signal from the VSS then transmit a new signal to the ECU/speedometer.

This is just one such company.

You could try www.ddinstruments.com and see if they have any recommendations for you.
