Floaty, Vague Rear End
Posted 27 June 2017 - 09:12 PM
Time dropped the suspension a few mm and ever since the rear end of the car is stepping out mid corner, feels sloppy almost as if your towing a trailer.
30 mph and a few turns left and right it's as if the rear end is a few seconds behind. I hope I'm making some sense here.
I've been running Gaz coilovers, rebuilt 309 beam with solid mounts for a few year and been perfect till now.
No clunks or bangs almost feels like rear wheel steer

T1R has a much softer carcass and a harder rubber than the R888 so they need a bit more air in them.
are the sills level or raked with the rear higher?

Tyres are scrubbed in well

What pressures are you running?

I have the t1r on my track car and also feel they give a loose feel to the rear end, i think it is the softer side walls.
Also swapped from toyo 888 and yokohama advan ao48's so a very similar comparison.
I think the t1r is cheap for good reason, on a wet day at rockingham the rear end was steeping out on the sighting laps.

Just out of interest welshpug, do you think its better to have a slight rake on the ride height from back to front then? Gonna try a few more psi in them myself after reading this.

they did as standard and do work very well retaining that so yes I would recommend it.

I've a feeling raising the rear may not help with the vauge feeling that the tyre change has created.
I agree with that yes, just because a tyre works on a 1300 kg 4x4 vehicle in a different size doesnt mean it'll work on a 875 kg 2wd hatch, personally never liked that tyre myself.

I had them briefly on mine and would never buy them again. Fortunately mines were the type with a red pinstripe on the tread, which was a specification for a race series of a young local lad and he took them off my hands. I think the other colour is green, and I think the pinstripe determined a slight difference in compound.
Even joining motorways on long bend slip roads I always had a feeling the back could go at any minute, horrible sensation.
Can't remember exactly what I set mines at after various combos and measuring but fronts at 27 and the backs at 28 (warm) springs to mind, and after a little bit of excitement they both settled in the low 30's.
edit, and they're no use on a track either, like they're sometimes advertised for.

Car looks stunning but correct forward rake is essential... as is tyres on a 205, you must have a fairly stiff sidewall or you are wasting your time.... and also maximum tyre pressure, it is impossible to heat the rear tyres on a road going 205 anyway. Think about it logically, how can you balance a FWD car under power that is higher at the front than the rear?

Lift it up 25-30mm and see how you go. A thicker rear ARB can be adventageous.
This is all therotical from personal experience. See how you go.
