Out in the parking lot playing around. The car likes to swap ends under acceleration. I would like to get more rear droop but the springs are too stiff. I set ride height and preload and get maybe 1 to 1.5 mm of rear droop. I'm running yellow fronts, kit rears. The beige springs seem softer than the reds. Ride height is 5.5 all around. I'm running internal stops in the shocks and the shimming preload with the spring spacers. If I take out the shims, I'm left with slop. I'd really like to find a longer, softer spring to allow more droop. Do I have to go aftermarket or is the a set of soft springs that works with the CVA shocks? I'm sticking with the CVA set as they are TCS legal for the class I plan to run.
MST 29mm springs
They are sold in pairs or in Sets of 8 springs. Maybe Set 820113 can be a good starting point for you: 820113 (buut no guarantee that they will have your needed characteristics)

liljohn1064 Have you tried the kit springs in the front and yellow in rear? Or yellow (that come with the CVAs) all around? I think those silver kit springs are stiffer than the yellow springs, which is going to make the car tail-happy.
Even with balanced springs (yellow) all around, I find it's relatively easy to get out of shape putting power down coming out of a corner. I suspect that the kit tires have a lot to do with it too.
OTOH, with only a torque tuned motor, changing to super sticky tires will eliminate any drama involved in driving this thing.

So I'm currently building the Tamiya TT02 universal shafts ... I machined this aluminum ring and attached to each universal wheel axle with some superglue. To capture the cross joint's pin and prevent it from coming loose.

I bought the SkyRC GSM020 GPS a while back ... I wanted to track how fast the TT02 can go with a 19 turn, hand-wound brushed motor and 7.2v Ni-MH battery. Yesterday I changed to a 29T pinion and 55T spur gear (4.931 FDR) and put some advanced timing to the motor ... today it tops out at 37mph. Not bad.
The stock TBLE-02S ESC couldn't handle the motor anymore at this gear ratio though. I swapped it out with a Hobbywing QuicRun 1080 and it's working OK so far.

How do you take it apart in case of a damage or a needed repair?

Has anyone seen that Tamiya is selling these Mercedes CLK TT-01E kits again?
$115 is hard to beat

after one year not using my tt02s I upgrade the adjustable suspension block from the rear SR and the new aluminium steering... tomorrow I shorten the body posts and setup and race this weekend! I will see if it make the car better or worst

That custom pin retention ring is a great idea. FYI: Acetone can break down super glue. Just don't use acetone on Tamiya ABS plastic (such as the wheels) unless you want to totally dissolve the plastic. Just be careful not to let it soak into your skin.
