Setup wise, here is what I managed to achieve after several testings :
Front
- droop : 5.4mm (measured with shocks mounted, and adjusted by putting shims between the piston and the shock body onto the shock axle)
- spring : SMJ 3.1
- Shock oil : 500cst
- Shock position top : 2nd hole from the top of the damper stay
- Shock position down : Tamiya 54943 in position C (i.e. : the most outward or closer to the wheel side)
- Camber : 1°
- Roll center : 1mm shim under the ball on the inner side / 0,5mm under the ball on the outer side (wheel side)
- Toe : 1°
- Ackerman : 1mm shim
- 1mm each side between wheelhubs and tyres
- Ride height : 5.4mm
- Spool
Rear
- droop : 4.6mm (measured with shocks mounted, and adjusted by putting shims between the piston and the shock body onto the shock axle)
- spring : SMJ 2.9
- Shock oil : 425cst
- Shock position top : 2nd hole from the bottom of the damper stay
- Shock position down : Tamiya 54943 in position C (i.e. : the most outward or closer to the wheel side)
- Camber : 2°
- Roll center : 2,5mm shim under the ball on the inner side / 0,5mm under the ball on the outer side (wheel side)
- Toe : 2.5° (flat, no skid angle)
- Ride height : 5.7mm
- Gear diff filled with 5k cst

Indeed, my car with the above setup is able to turn into high-speed corner at full speed, but struggles to maintain its speed : I can litteraly see the car slowing down throughout the corner (I'd say starting from end of entry / begining of mid-corner) even if I'm full gaz on the radio still (no slight slow down nor braking input). A fellow racer with a Schumacher Mi8 was able to carry much more speed than me within the same corner whereas he got the same top speed at the end of the straight than myself and he full speed turned in as well.
Thanks for your ideas !

You'll never be able to adjust the car to carry the same speed in a corner as an Mi8. The true measure of a race car is its ability to change direction, not straight line speed.
What you are sensing is likely the affect of the structural and component flex of the predominantly plastic car you are driving. The plastic chassis will flex so much with the corner forces that it will cause the tires to grip more and scrub speed.
That's the fundamental performance gap between an inexpensive plastic chassis kit and a full performance race kit with carbon fiber and aluminum components.

That could be, but my SRX is equipped with the TRF420 suspension, SSBB+ dampers,... Basically, the main tub is indeed plastic (hard version), but if it really is the reason why I loose so much speed going full gaz into the corner, then I'm a bit surprised (and disappointed)

Wheels
Finished the wheels for an upcoming TT02 project that will have a BMW M1 Procar body by Carson in Germany.
Didn’t like the “toy car” looking chrome on the stock wheels-fixed that with flat clear on the rims.

Yesterday I made a comparison between the Tamiya TRF421, the Associated TC8 and the TT-02 SRX.
The SRX was extremly close to the high end cars, but the lap times with these were a tenth faster and a little
more consistent.
Not bad looking at the price difference...
By the way, all three were equipped with the same body (BD Eptron), motors, tires, batteries...

Hi there,
here is my setup for a TT02 SRX fully hopped-up for a large outdoor asphalt flowing track : https://site.petitrc.com/reglages/ta...avez_20250921/
Feel free to reach if any question

Guys got a question on my tt02R I have been running it a lot for tcs and now that tcs is over we have a super gt class that I am running it in, we run the the hobbywing just stock 21.5 setups in them blickey and fixed timing. we are required to run the ride 2426 tires (so not sure what shore rating is). I have some upgrades on the car, Tamiya universals on front and rear, Trf shocks (30mm length to get ride height at 5.5mm), also has carbon fiber shock towers, and carbon driveshaft.
My setup now is 5.5mm ride height, 40wt oil in shocks front and rear, yellow springs on all 4 corners, 2.5 degrees of toe in rear, and 1 degree of toe out up front, 1 degree of camber all the way around, 500,000 in front diff and tamiya AW in rear diff. Gearing is 64p 74t spur, 55t pinion
The problem I am having is car is hopping in rear on corner entry and not sure what I should do to fix it. I know with my mini z experience when they hop in the rear you can usually fix by softening up the rear, not sure if it will do the same on the tt02. Any help would be much appreciated, and please just let me know if you need any mor info on my setup.
Thanks Rick
