Yes, typo my side on the number there.You need to check the size again as I think it should be 255/35/19.
You've got a rear wheel drive car which I understand now has almost 400bhp. I think it does need to be something good, you clearly care about the performance of your car otherwise you'd not have bothered paying so much for those upgrades. So why then compromise on the area that will make the biggest difference to the handling of the car?
It's not even that much more expensive for decent tyres against something like the Rain Sports.
For example, for 255/35/19:
Michelin Pilot Sport 4S: £165
Continental Sport Contact 7: £148
Rain Sport 5: £113
£35 a tyre really doesn't seem like it's worth the saving on a car like yours.
You will want to match the front tyres too, but this would apply to any tyre you'd select. What does it currently have?
It has sport contact 5 SSR at the moment.
The rears let go a little too often as it is, so an upgrade would be nice on the rear. I think I'll get the Pilot sport 4s, as I understand those are modified version ls to suit these cars?
Where are you seeing those prices? Looking mote like £200 a pop here.
