WARNING . If you get the clamping front axles check the inner bearing seats all the way on.Mine had a ridge and damaged the bearing and is now notchy,This happened during installation, car has not been driven. While at hobby shop exchanging it and buying new bearings another guy there overheard me and said his does the same thing. That is 2 sets that were bad and there is probably more.

less trail increases steering responce or faster steering but not really more steering, personally feel car drives more consistent with 4.

smoother and has the same amount of steering.

Stupid question, but did you install part 91414 rear hub spacers as called out in the instructions?

For a neater wiring job, did anyone consider to route the motor wires under the battery where the sensor wire should go…? Obviously some modding required incl the chassis, and possibly limited to 14G wire… any purists out there?

The bearings are an issue, clamp or no clamp. I don't think it has anything to do with your install.

it's not the clamp it was a mismachined axle for the clamping hexes, i havent driven the car yet.

I disagree. The manual states it adds entry steering, and I found that, through back to back testing with my B5, that it, adds steering there AND almost everywhere else, including corner exit and long sweepers.

wayne, did you feel like you had to much and it would over rotate the rear end at all?

good info right now, i do plan on testing trailing ackerman, when i hit the track, are your running the a hub in the rear? up or down and any washers on the back ball stud?

It is pretty darn aggressive at 2mm. Serious. Some of us who did this change went back to 4mm. I still have it on my car and am not sure if I'm going to keep it, go to 3, or back to 4. Right now, my car is poop for high traction, but on a drier track with low traction, 2mm felt great.

Honestly, I think it's a "as conditions permit" thing. With traction, it's a hand full. With low traction, it's a God send. It reminded me a lot of caster and ackerman changes, except noticeably more extreme. A 2mm decrease in trailing axle is probably a good 2-3x difference that a 5 degree change in caster would produce. It's a pretty big hammer.

awesome,thanks for the insight,tracks here in so cal are normally really good in traction and smoothness,we have two large indoor tracks and ocrc which is high bite and where they ran the reedy race,so racing is good here in so cal

hey guys, now that some guys have had their b5m, what have been the thoughts on b5m vs c4.2, i have a decked out c4.2 and its great but i also have the chance to buy a b5m... or b5 tonight... in winter i run on indoor carpet and in the summer we will be running on a clay track outside.
