miket3 I am using the kimbrough medium (reference 201) with no problems, and it's way cheaper than the xray one.

What are you guys using for offset spacers? Also, I was on a carpet track yesterday that is med/high bite. I found myself fighting the car from traction rolling troughout the track. I'm running a 17.5 blinky box setup with black/grey (f/r) springs. I'm going back this weekend. Should I start off with Gary's Vegas (http://www.petitrc.com/reglages/serp...IIC2012100106/) setup, or is there a better one I should start with? Thanks

Are you guys using standard or ceramic bearings throughout the drivetrain of the car?

Hi Ron, you can use either the Tamiya spacers or the Xray spacers, if you use the Xray you will have to ream the holes slightly, the Tamiya will slip right on without mods. The wider stance will help with the grip roll issues, but also take note of your tire doping, how much, how long and what kind your using will help to cure some of the roll problem to. The Vegas setup is pretty good, although I'm still not sure what you'd really call the grip level of the carpet, but then again, we had some unusual Jack The Gripper that made for some strange goings on too.

Lots of people will try to make the car really soft to stop the grip roll problems. Martin even suggested to have the car so soft that it actaully would run on the chassis in the hard corners and skate across instead of digging in.

I would try the Vegas setup, but loose the anti-dive. If anything you could even go with bigger hex spacers, like 1mm in the front and .5mm in the back.

I use the standard bearings that come with the kit.

If its your own setup maybe post it then we could see if something else is causing the problem.

At what point of the turn are you traction rolling.... is it a quick roll right at corner entry or mid to late corner during full weight transfer? This can help determine many things in terms of where to go with adjustments. Also... interms of set-up. I found the kit set-up to be too aggressive on carpet. Try startining with Martin Crisps Canadian Champ set-up. The track was medium bite and with that set-up pretty easy to drive.

37502 = Stiff
37503 = X-Stiff

By far my choice in servo savers. Reliable and durable.

Just an update.

Went to the track last night after the tracks GM finished Thanksgiving and the 2 of us ran laps late into the night with our TC's.

Track was cold, temp at the carpet around 61*. Running well used Sweep QTS 32's (36 batteries on them previous to last night). Front end felt like it had a little too much grip and was overworking the rear. I could induce traction roll with too violent of a steering correction, especially in the chicanes. Increased the spacers on the rear upper outer links from 1mm to 2mm and moved the front upper shock mounts to the 2nd hole from the outside. Car felt really good, but developed a bit of an on power push. One thing I have not tried yet is running a wider front front block and a narrower front rear (called arm sweep I think?). This would build toe out into the suspension geometry. I would still run 0.5* toe out on each side, but I am wondering how this might affect the on-power push? I might also drop the shocks back in a little, as the rear roll center changes might have been enough.

I am running 2* blocks front and rear on the front right now, and would probably do 2.5 front, 1.5 rear to try and maintain the front track, and then adjust from there.

I also broke both rear arms (2 seperate incidents) last Saturday. Replaced the hards with mediums (all I had left), and the car got slightly lazier in the rear, but actually felt a little more stable. I am definitely losing rear traction by the end of 6 minutes, and actually will sometimes get an almost uncontrollable snap out of the rear end when I get on the throttle too hard out of a 180*. Would thicker rear diff oil possibly help this? I am still running 100k front, 2k rear (have not sourced the thicker front oil yet).

I would have thought the opposite, but let us know what you find.
