I do not recommend the Tworks steel shock standoffs. I had one of them snap off yesterday in a minor crash and since they don't use replaceable bolts it cannot be fixed.

I had a older set that never had a problem with. Bought a new set for the 8 and they're a little short so when you tighten the nut down there's no play. Had to spin the nut around to get some slop. Tossed them and put the stock back on

Hey guys just getting back into racin, still got a 7r. I always thought the car needed some more steering. I was wondering if the "-3mm front upright arm" Part # MUGE2168, made a difference while on power mid/exit turning. Thanks for any advice

It's gives the car more overall steering. The entry steering is more aggressive and the exit is smoother and more predictable, but the you'll have more steering.
I have also found out that the -3mm steering plates allow you to run higher front diffs fluids so you gain a bit more on-power steering while still having enough turn in and mid corner steering.

if you use this -3 you use e2147( more steering initial and more reactive)or e2146 (more steering in the middle and less reactive initially)

Always use E2146 with the -3mm plates. E2147 is too aggressive combined with the -3mm plates.

Hey guys, another question on the new uprights. I'm still using the universals, so what size bearing do I need since the 8x16 obviously doesn't work. I've spent way too much time searching the web for the bearing size. Thanks for any help

It's 8x16x5 for univerals and 15x21x4 for the CVD's on the inside. The outside bearing is the same for both type of drivetrain and that's 8x16x5

Wow I feel really dumb, I thought I needed a 8x21x5. I never even tried to fit the 8x16, I just figured i needed a bigger bearing. Thanks a lot morgoth

No problem. The hubs should have a hole for a 8x16x5 bearing and a bigger groove for the 15x21x4 bearing.
If you have a normal mbx7 hub (not R) then, you can only run CVD's. The updated hub for the mbx7r and mbx8 accept both types of bearings.

Hi guys, could someone measure the distance between the front chassis holes at the front of the chassis? The ones which connect the diff housing at the front?
