previous best to date was @ MIR: 12.425 @ 108.93, w/1.67 60' (DA was approx +188 ft). Car weighed in at 3660 with driver and gear (1/2 tank of gas, gutted trunk, full interior). Strange struts/shocks set to full loose up front and +4 clicks out back, rear tires set to 18psi. UCA in upper hole on UCA mount and LCA's in uppermost hole on BMR relocation brackets.

The air was amazing at MIR tonight, the DA for my last run was approx -1500 ft :boobies:

For this round of testing the car weighed in at 3680 with driver and gear (1/2 tank of gas, gutted trunk, full interior and misc gear that I didn't leave unattended like at previous track rental). Front struts set to full loose, and rear shocks set to +3, rear tires set to 18psi. UCA in upper hole on UCA mount, and LCA's in middle hole on BMR relocation brackets.

My two best runs were:
12.496 @ 107.93 w/1.657 60'
12.479 @ 108.18 w/1.652 60'

I'm disappointed that my car didn't do better with the killer DA. While my 60' dropped from a 1.67 to a 1.65, I was hoping for much more... GoPro vids showed slight lift of the front wheel on most runs, no dice on the right wheel :yuck:

Don't get me wrong, I'm thrilled with 12.4's (302 rwhp, full interior, OEM cats/emissions tune in place), but we all want a little more right?

I think I'm done for the year. Winter plans include weight reduction, and some skinny front wheels/tires. I was considering Viking double adj shocks, but I might have reached the limit on 60' with my power/weight level. I can probably squeeze a bit more out of it with my Strange single adj shocks.

Damn that DA is ridiculous.

However I would think hooking in 41 degree weather would be a challenge.

yea, there were quite a few folks taking advantage of the DA that night :thumb2:

here's a shot that was taken:

The vid shows the left wheel got a bit of air, but no joy with the right one this time...

thanks! I'm still learning how to drive (I don't even do a proper burnout), and I'm spoiled getting to run at MIR.

I hope to pull some weight out of it this winter, and get some 15" skinny front wheels/tires; otherwise I'll just continue to dial in the shocks/struts and tire pressure.

ETA: forgot to include lpw diff cover, competition engineering adj panhard bar and dual drive shaft safety loops on the mod list

^nice!

had the day off of work (building had water issues so it was closed down) and I drove up to JPC Racing. Aaron let me up into the 'garage sale vault' and I picked out a V6 cloth seat. going to ditch the heavy power seat controls and mount it on a manual slider/track and have it on hand for track rentals.

the OEM cloth seat with slider will be ~35 lbs, and I don't have to worry about having a crossbar (or cage) to tie-in/brace a 1pc racing seat. Ditching my power leather seats and rear seat equipment will help with my weight loss goal.

thanks again Aaron for letting me stop by!

Nice run! That is a great camera angle. I never thought of it before. I am going to give it a try 6 months from now when my local track opens.
