360 - horrific understeer
Discussion
I've driven F355s/550Ms hard and always felt they were VERY well balanced.
Well I drove (at customers insistence) a mildly tweaked 360 like I meant it for the first time today - we modded it to run around an extra 25hp, snappier F1 box etc.....
DAMN!!!! THE 360 understeers like a F****** PIG... Brake in a straight line and although the turn-in is instant, the car just wants to wash out and out and out..... putting your foot in harder makes the understeer terminal.
Lift a bit and the back comes round immediately..... so basically if you go in too hot.. you're dead..
Anyone agree?
All in my opinion of course.
P.S. ASR is for wimps.

I've never driven a 360 so can't discuss the minutiae of it's handling, but were the tyre pressures set correctly? I seem to remember 456mgt writing a post once mentioning adjusting the tyre pressures on his 360 made a vast improvement to handling.

PS - Did you get my email yesterday.

Nahh- you're just a shite driver Manu!
Noooo- only kidding, honest
You & Ajay have both been on some hoons in the 360 (until, like a moron, I sold it)- did you notice it understeering much? I can't say I did. If anything, what I noticed going in too hot was mild oversteer, which becomes 'holy f***ing shit this is oversteering' when the tyre pressures are wrong.
Other things I can think of are cold tyres, shagged tyres, greasy road, wheel alignment and/or tracking out. You hadn't just siliconed the tyres by any chance? The only other thing I can think of is that you went in so hot you simply overcame the available grip, in which case the car may have saved your ass. I'd dispute the view that '360s understeer' period. It's a fast car point to point, which it wouldn't be if it was too understeery. In any case, I think the 550 & 456s are more likely to understeer than the 360. So there! Nah nah neh nah nah
And what's this "ASR is for wimps"? Takes a lot of confidence to switch it off I can tell you, and you certainly won't do it unless you've had your sphincter tightened.

I've been racing (Mechanic) up to 9 different challenge cars, and 3 different N-GT chassis to date.
Admittedly, the factory shox on the challenge cars are the first things to go in the bin, but basically, the chassis do not have an under steer tendancy.
We've also had several different professional drivers in road cars, on road tyres. There is a mild tyre understeer typically, but classic correct driving technique makes this minimal and easy to dial out with small geometry adjustments.
Poor technique, namely excessive corner entry speed, is THE MOST applied mis-demeanour, and cause of slow lap times.
Sorry, Manu.....shite driving it is.....
It's slow in, fast out, and imagine there's an egg on the throttle pedal you mustn't break.

Thought as much... still.. what you're saying means you've got to trundle into corners like a limp-wrist..... Oh well, when the time comes I'll have to get something that can just go in FASTER..
Mind you most people that I know who have driven the 360C and the road car think the comparison is totally invalid - the 360C is a COMPLETELY different machine...
