I don't know if I should be concerned or happy.....certainly smiling when going for my second drive in my GTR
And the rear end swung out slowly in second gear around a round about with some acceleration and then rear wheel spin in third around a bend under acceleration............cheapish tires fitted by previous owner and cold outside and tires cold.
Certainly not scary as it never felt on the edge or out off control if you know what I mean.......

OK......is this normal as I am used to AWD and smaller engined performance cars and scouts honor I did not have the pedal to the metal.


PS:
Also I had 28psi in all wheels.....LS1 with G50 box.................may need to short shift....?

28psi way to high.

you will now get lots of answers about best tyre pressures.

mine are 17 front 19 rear.

You might also want to check your right side planar flexion. If the default setting is two high it can lead to traction loss at low speed corners. smile

Check yours and see if a level of modulation is in order.

But from what you describe, it's an easy fix. silly

I have a sticker on the car that reads 200kpa. Front and rear cold..........?
Never heard of a car with such low tire pressure.....is it due to the extra large
Tires........?

No...No...read the manual! readit

...it is adjacent to the quasar photon modulator, just poking out to the side of the tri-catch demulsifier!

Gunter, Glad you have it going. I wonder if a lower tyre pressure would have helped in the Exige the other weekend as well.

I came across this article the other week
http://www.racetechmag.com/articles/article.php?id...

I have the second part in hard copy as well if you want it. Makes me wonder if ducting the front radiator out through the front wheel wells would improve heat retention into the tyres and allow for some extra grip.

Hey Ryan......

I still have to change some CV boots and get one of the wheels rolled as it has a slight ding in it......other then that
All good.

Tire pressure was all good on the exige that day but I think the rubber is gone off......5 year oldsmilesmile
Still felt ok but.......wasn't loose in some fast cornering.....just getting harder to get heat into the compound when it
Matures.......

lower presures should help with the temps.

True...can't argue with that Ryan.....just always gone with manufactures recommendations ......
but will have to go below 20psi on the Ultima.....to much torque and a very light car.

My first few drives had me slipping and sliding the rear (not helped by new brand new tyres). That taught me the respect to take it real easy and build up confidence over time!

After 18 months I still can't say I'm totally confident with nailing it in 2nd or 3rd gear on the road!

Yea I will be extra careful in the lower gears........but to be fair to the car it didn't catch me out or get redicously
Out of shape.........but could have in the wet.

Yep......LSD would be the go as I 'm sure oversteer would still be on tap with one fitted......
