Yep Tamiya 42259 worked for me too.

Hey Guys,

Just curious if there is a trick to getting the ride height lower than 7mm? I am using associated springs currently, is there a shorter spring available these days? Also, I have been out of racing for quite some time and the gear diffs are new to me. The kit called for 1k fluid and while it feels smooth and doesn't hang up, it feels pretty tight vs ball diff standards. Is that normal or should I try a thinner fluid?

tqrcracing.com has the 20mm shock spring set from Spec-R, for the S-2. The tight feel in your diff may be caused by the orange O-rings swelling too much. Search this thread for fixes. Good Luck.

Thanks Mooby,

They recommended the Tamiya short springs so I ordered a set to try.

after building 5 of these kits finally got the bad one, 3 turnbuckles not threaded on on side, a wheel nut that does not fit, luckly I have so many parts and the build went well, I have one for each family member, now if we can go racing

Got a part number on that? The only thing I see is for big bore shocks.

Thanks. That was the one I meant though. Do the big bore springs fit OK on the kit shocks?

Took the rear diff apart today and sure enough it was the orings that had swollen so bad the diff was binding. Kind of disappointed that it only took an hour of sitting on my bench for that to happen... Thanks for the heads up Mooby.

Just get the TRF o-rings mentioned elsewhere in this thread, and you won't have any more problems.

The springs seem a little short, because you have to run the adjustment collar down pretty far, but you still have plenty of room for setting ride height.

As for spring diameter, they fit fine.

Cool, I will try those. I wonder if that is what they intended to ship with the S2? It's still weird to me that they would ship the car with springs that make it impossible to run a decent ride height for racing. It's like they never built the whole kit to test it.
