Thanks for the info Laze. I've been running 38 psi hot so I'll try the higher pressure. Checking ride height this weekend; installing brake ducts and the longer ARP studs up front due to the massive spacers needed for the RPF 1's. Should be interesting...

 

review this Tuning Guide from BFG

Also, I have been informed that the new 2013 Spec Z rules will be out soon and they will include provisions for brake ducts...and with a defined air intake hole that can be cut into the bumper...so you might wait a week on the brake ducting or install it today with the option of changing it soon

But we will not know for sure until the rules are published!!!!

Nick, If you want to come to a NASA-SE event I will be happy to help you Organize a demo/sales area and maybe host a technical seminar...u can give away some Hats/Tees...get some "mind share" with the NASA-SE crowd. Maybe Sponser a Spec Z race and give away a $100 Coupon to the Spec Z winner or something...

Road Atlanta always has the best attendence on the schedule...with spring and fall events being highest.

Lemme know if this makes sense for you.

 

John,
Ken and Nick are right by me, and they can be at CMP many times. I can vouch for their service.

 

Cool! As you can see I am attempting to get Sponsers involved in Spec Z...I have some other things I am working on..like a "East Coast" National Spec Z weekend @ Road Atlanta in September for those not going to F-ing Utah...more to follow

 

We have been trying to work w/ Jeremy from National but nothing has happened yet.

 

Understood...I can tell you NASA-SE is happy to do something that is on the appropriate scale...I will be in touch.

I find it amazing what a couple hats/tees give aways and FLAG GIRLS will do

 

I still know some college girls that I'm sure will be some flag girls

Excellent! We are gonna get along very well!

 

Hey wait...that was never offered to us!!

Man, you guys get it all. We don't even get trophies.
