Juste received my tekno springs, fit perfectly, a little tight on the collar but it fits. I ordered the green ones, a little stiffer than the boxed TD. Extra length allows me to reach the ride height of 40mm rear 38mm front (and have horizontal arms).
Still bottoming out a little but much better than with stock springs.
Also changed oil in my diffs from 7/10/3 to the recommended 5/7/2, this has not solved the nose lifting/plunging a lot on acceleration and brake...
Otherwise, can't seem to get this motor to heat, I am now up to 17t and hotest I have had after 15 minutes was 114F, esc 98F (Tekin Gen2/t8 2000KV) on 4S.
It has some speed/torque but I'll push to 19T and see how it goes from there.
Quick note, I ordered the 19T long shaft pinion from Tekno and unfortunately it does not fit, shaft hits on motor mount and can not go all the way in.
For spring reference:
