Your kit should have came with different antisquat shims. Its really easy to change the antisquat, but the shims pop out from the brace pretty easily after a run or two.

Yep I put the older style ones in . I did that when I built the car a month ago .

I've got a bit of a different question for you guys and I apologize for asking it here but I know you guys can probably answer it. I don't have a B4 but I do have a project that may use B4 parts. I'm trying to find out what the hole spacing is on the 4 screws that hold the front bulkhead onto the chassis. What is the spacing from screw to screw going side to side and from the forward to rearward screws? Hopefully that description makes sense.

Yep, that was it! Last time it came loose, this time it went the opposite way. Dodged one there, had zero intention of opening up the tranny box..

Thnx guys!

Thanks.. but didn't get a kit, I got a used B4.1 and got zero parts with it... so I need my to eblocks and antisquat shims, so i bought the whole kit from amain. Good to go!

ae made a running change to this. I just built a fresh kit and the shims arent "open" anymore so they wont fall out.

How long ago did they make the running change? I built my kit in March, but these damn shims wiggle out every heat race it seems. Can't complain on how easy they are to change though.

I bought a FT B4.1 right after it was release, and I do believe the anti-squat shims were open. I bought a new FT SC10 two weeks ago and those were not open. I just cut out a section to make them open. Just make sure the bolts are tight and they should not come out. I have noticed sometimes those do come loose after some hard landings/cased jumps.

ya i just added a little ca.

I just built my FT B4.1 in May and it came with the open anti-squat shims . Running Change Buy then separately .

what settings are you guys running on your lrp sxx stock spec. willing to try em. and on b4.1

My chassis cracked tonight right where it mounts to the bulkhead..just on the part of the countersunk screw fitting..glad every damn place is backordered

Ebay is your friend.

Thanks for the suggestion, but that's the first place I looked. The only one on there is almost $40 and is located in the UK.
