Is there really a 3.90 gear for the 8.8 now?

Guys who makes this 3.90 gear?

PKRWUD · 05-17-2002, 10:53 PM

I've never seen one. There's a 3.89 for the 9", but I've never seen one for the 8.8.

Take care,

Hey Pkrwud, I see you run dirt track?

Does tire compound matter in your sport?

PKRWUD · 05-17-2002, 11:25 PM

Almost as much as tire pressure. It really amazes me what a huge difference there is between hard and soft tires!

Take care,

Get with the times

You need to go with some 5.13 and don't waste your time with the 3.90.

Hehehe, children. We ran 6.63's tonight, but we should have left the 6.86's in. Kept us from winning.
