More grippy tyre only front.
 

Hi,

I'm new here. I'm french
I was thinking to put more sticky tyre in front like Michelin PSS in 225/45/17
and keep the primacy 215/45/17in the back.
That is to get better turn in than the primacy at 4 corner but still that happy tail car and as much fun and free tail car as possible.

I have had mostly owned high powered 4WD (subaru, Audi) car. On all my car I will run much wider front tyre. My audi 450 hp is running on 265 wide tyre front and 235 in the back.

I'm not racing my car or tracking
Mostly doing Very very fast mountain road late at night for fun. Rally style a la Sebastien Loeb
Want max fun don't care so much of being .5 second faster.

What do you think of such set up?

By the way I'm not a young hooligan I have 30 years of spirited mountain rod drive in my back ground.
Would have dream to do rally but not enough money when I was young.
Now got the money but to hold to hope for any carreer in that.
So just enjoy as soon as can around my place. Lot's of wonderfull narrow montain road.
It's the Rally Monté Carlo area.

No reason it's not possible but I'd looknat adding front camber first, then fine tuning to the suspension setup, before trying 'reverse stagger' setups (unless it's just for kicks).

Also a possible risk of it becoming tail happy in exactly the way you don't want if you do stickier tires up front. A really loose rear might be fun for pitching it in hard to tight corners for drifting and/or powering out of tight bends but on the flip side it might become highly unstable at rear (and impossible to catch) in high speed bends, especially if you lift while cornering at high speed. Think early 80s Porsche 911 style.

If you do try it out, let us know how it behaves though. Might be fun for certain diving styles or roads for all I know.

There's no reason it would become LESS stable. You're not subtracting grip in the rear.

There ARE other ways to get the rear loose... the car responds exceptionally well to e-brake application.

Thank's for your answer.

I don't want to get the back more loose I just want to get front more gripy

Sorry prees enter to quick

I mean keep back as it is "drift on demand" and get front a bit more gripy fro less understeer.

Your background seems to be typically understeery AWD cars. You will find if you haven't already that the car is much more neutral to oversteer out of the box than your previous rides. If anything I would recommend driving it stock for a while then trying some suspension tuning to get to your desired result.

There's nothing to stop you doing it, but try the car stock first.
