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...
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!!!!

Just wanted to drop in a little reminder, we know the season is going to be starting up quickly soon, and everyone will be preparing. But I just wanted to remind everyone that that we will be doing wholesale discounts for those who are running Spec Z, feel free to shoot us a PM or email at sales@knsbrakes.com

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.

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