yeah, I ordered some durango wheel nuts. I really like my avid wheels, so this is great news. I really didnt want to buy JC wheels. I hate that matte finish


Ok, are the front caster blocks marked? I have a few sets of caster blocks and want to figure out which is which.

I really like the avid products. You should see my b4, it covered in just about every avid product including bearings. I just picked up the K car and good quality upgrades that are not overly priced are far and few between right now. For instance, I think your new stand offs for the b4 in a rb6 version might go over well. I have an avid slipper and will probably get the avid rb6 top shaft eventually. I am sure you guys could also make some nice rear suspension holders that are of good quality and not priced through the roof. Anyway, looking forward to seeing more from AVID.

Black or red; those are my new colors! I'm tired of the blue!

Guess I'll check out Yaiba or STRC's Red ones for the B4.

The pin brace and the suspension holders are nice upgrades. I think the weak rear camber block was updated for breakage. I assume the plastic hubs hold up ok.

I don't know about your guy's experience with the RB6, but one thing I like about the car, is that it seems like the car just flat out works. EVERY setup I have tried on the car, just works (at least on my high bite track). Naturally I can shift the car's behaviour one way or another with different setup changes, but I have yet to go to a certain point in a setup that makes the car NOT work. I hear (and see) B4 guys that have the wrong setup, and their cars don't work well at all.... once they get their setup correct, their cars work great. I can't get this car to "not work"... if that makes any sense.

For example, I have gone from Gold/Gold, to Pink/Red, oils and pistons ranging from 40 down to 22.5, short wheel base, long wheel base, 25 up to 32 caster, with 25 kickup or 30 kickup, long pack, short pack, low roll center, higher roll center... and EVERY setup, simply takes me a few laps to get used to, and I am right back on pace... none of them have made the car feel like it had a bad setup on it.

just me?

The inserts that go into the caster blocks are marked. I believe there are 0, 2, and 4 as options.
