good times man, those 20's were really killing you.

 

yep, big drop, congrats! Rotational mass is a *****!!

 

Was gonna run some spares on the front, but Jon's Escalade spare was a 16 with some kind of all terrain tire on it. And I didn't have access to another 17" one.

The 20s weighed 84lbs, the 15s were 51lbs. The spare was 65lbs, so if I get get them on there it would be another 40lbs off the front. The DA was better also, ~ -550.

I'm surprised it didn't help the 60' in more than it did. It just needs more stall.
