Exclamation Loose rearend 8ight 4.0 buggy

Would the addition of the TLR rear 20 g chassis weight help with the loose rear end on my 4.0 buggy , I'm running 1000 in the rear diff , 2.3mm rear sway bar and the stock 4.0 kit rear shock springs with 30 wgt oil with the stock kit 1.2 - 1.3 mm split rear pistons .Now I know my heavy throttle finger doesn't help but wondering if the addition of the chassis weight would help settle the rear down a bit

First off, thry posting in the dedicated 4.0 thread. You will get a better response than starting your own thread.


Second, where are your camber links at on the tower and hub? What kind of track? Whats your rear camber, toe and Anti Squat set at? What kind of tires are you running? Are the similar to what the faster guys run? These can play a huge impact on the car...


Also, Have you tried the kit set-up yet? car has a lot of rear end grip using that set-up...

From what I saw on the weekend, I would recommend looking at rear geometry first before looking to add weight. Run the minimum amount of anti-squat (#1 insert with the hole down of the C-block = 2 degrees on anti-squat on the 4.0), and 2-B for the rear camber link. This should have plenty of roll & camber gain and give good on-power grip. The other thing to check is that the arms and camber links are all free (ie fall under their own weight with the shock detached).

Reducing antisquat can help lock rear in.
