Xray XB4 thread

Rear grip is my problem. I own a B44.2 as well, but bought the XB4 as my next move up. But so far, for me, I havent had much luck with it. The B44.2 is so hooked up with stock settings, it is a joy to drive. Despite many attempts, the XB4, though a ROCKET, can't keep the rear planted, even on the straight. It does sound like less anti squat may help. Did you take the angle off the FR or add angle to the RR to reduce anti squat? I am not the best at setting up cars - I do rely on online setups, local racer input, etc. so your advice helps! No local racers for the XB4, though. I truly love the quality of this car so hopefully I can work out the rear end grip deal. I am blown away by its almost friction free drivetrain.
I look forward to hearing back.

I think I got that right, but I know on my touring car if I raise up where my rear arms mount it'll roll less on the rear and I'll get more rotation and vice versa. Although it might be a pretty small change on an off road car.
Also try adding just a little bit of rear toe, last time I was at the track I tried 3.5* and it seemed to calm the car down some and make it easier to drive.

Farm,
Indoor clay, medium to high traction. I have tried the stock clay setup, followed by stiffer front sway bar, progressive springs, the 1 dot rear springs with lighter oil, front 1.6 piston with 1.7 rear pistons (like my B44.2) with thicker oil. I even took the rear sway bar off once. The rear end skates down the straights, will swing the rear end out on the sweeper, etc. barcode gold fronts, HB Beams and barcode gold rears.
It's as if the rear end is spinning so quickly it can't grip. My B44.2 handles great. Same track, same more 6.5t), geared 18/81. But boy it is fast. For sure! I even tried a 8.5t, thinking 8 needed to take it down, but same results. I'm a bit perplexed, but I know once I figure it out, it will be a keeper.

Hi all, I raced my XB4 for the first time last weekend. Really impressed with the car, kit settings aside from the chassis flex (max flex). The track was very low grip and bumpy with an assortment of jumps. Motor was an Nosram 6.5 with a v2 in blinky mode. The car was really balanced and easy to drive.
My question is, how often are people finding they need to refill the shocks?

And have you tried shorter rear wheelbase, so that the 2mm shim is behind the hub?
