My best was a 49.4 with just a uppipe downpipe catback IC hoses and short ram.
I learned i should of left my tires at 44 psi instead of dropping the front to 38... they rolled real bad. My final run... was off course in a horrible way... I had brake fade and tires that weren't up to it.
A few suspension upgrades... and a stiffer sidewall and I'm sure I could of pulled a 45 like zoinks did.
(Talked to some really great people, and overall just had a great time, many many friendly people... plus no rain)
