Haha thanks, if I didn't screw up in the first turn I wouldn't have had to! Total amateur move on my part, but i was stoked I hit the 21.1 mark just doing the double.

I have the gold springs on it now and it seemed to help some but I think you and I were both experiencing some odd traction tonight. Thanks for the offer though! See you at the track soon!

What retailers are selling these in UK / US?

Do you sell direct to UK customers?

Always liked MIP in my XXCR Kinwald which I still race

We do have retailers out there but these were just released like yesterday hahah so the UK retails wouldn't have gotten them yet.

We do ship directly to you guys though We are only weeks out from the CVD's so if you do decide to make an order I'd hold off until then. Since international shipping a little more.

Track was super hooked up last night at West Coast Raceway. I had very hard time breaking the tires loose. All of the rb6's At the track are getting faster each week. I was finally able to get my steering back with the new front tires and once they broke in.....it was perfect.

Hi,

OK Cheers for the info.

RB6 diff is very very good, but certainly interested in some MIP love

Is there anybody that has ran their car at multiple tracks without drastically changing the setup. I've been thinking about getting one and plan on doing the jbrl next year, won't have a lot of time to get the setup dialed into each and every track with the amount of people that show up. I can throw my B4 down pretty much anywhere without changing much, if anything, and it's good. Thanks!

I run my car on both a clay indoor track with slicks and a carpet indoor track with wooden ramps with pin tires and I don't change my setup at all. In fact, I've only made one small tweak to the kit setup since the day I put it on the track the first time - it's so dialed out of the box you don't have to really worry about it!

i think i have really nailed down a extremely versitile setup. i have raced on 4 very different tracks and the car has been better then me on all of them with the same setup. as always tires need to be right but other then that the set up is constant. looking forward to motorama. I will try to post a setup sheet asap if any of you are interested.

Post the setup please. Any setup that works for us normal drivers would be really appreciated. Tires and practice of course is the most important.
