g'day all, ran my mtx4 on the weekend at my home track[medium size, low bite, bumpy suface] using purple springs, rear lower arm roll in mid hole 2 deg toe. car was verry loose on power, a fellow racer suggested i remove rear sway bar as i only have the 2.5mm one i did this and the car hooked up realy good, but rolled around in the rear a lot and needed to get some stearing back so i reduced the front droop to 1mm up from ride height and it did the trick as the car turned in to the corners quite good.
1st qualifier; started 2 laps down(the tz5p runs much better if i remember to fill the tank with fuel
you learn something new evey day
) once under way the car ran verry good and easier to drive consistently quicker than my g4 that i've been running for 18 months.
2nd qualifier; filled tank
car was still good and finished 2nd with 19 laps, 5.06 min, 2 laps gained from 1st qualifier and a personal best by 8 sec!
3rd qualifier; increased ride height to clear rubberised repairs to cracks in ashfelt surface(some rubbing of chassis in 2nd qualifier) got the jump on the field in the out lap and gapped them to win it and set another personal best 19 laps 5.0145 min to quallify 4th in the a main! another pb
a final; started off slow, took a couple of minutes to get on the pace as tyres wore down a bit, then got good pace out of it. after the third pit stop of the 15 min final the car started to go side ways out of the corners on anything but light throttle, just like it would with a stripped belt,but would accelerate in a straight line with no problems untill i get to the corners again.
it was still driveable if i took it easy at the corners and bends so i continued till the finishand was about midfield i think.
when i inspected the car todey under the light i found the belts had no teeth missing although the rear belt is a little worn on the back of each tooth, also the side belt skips on the rear side pulley when i turn the front or rear wheels with the other wheels pressed to the bench to stop them turning, pluss the rear side pulley is a little worn along the middle of the teeth.
is this the most likely cause of the spin out problem?
is their another area i should be looking at?
also is there a good way to find rear traction on this set up using a 2.1mm rear sway barr that will be consistent to drive?
any help would be appreciated
