So I had 225/45/17 fitted today... PS4's for around £65 a corner, which was insane value. ATS still have the offer, combined with top cash-back and halifax banking.
They are so much stickier... wow. Big big big difference. Not all positive, if anything the car feels a bit too stuck to the road. haha I know that doesn't sound like a bad thing but funnily enough it feels too safe now. But perhaps that's just as the tyres are brand brand new.
As a whole I'm very happy, the car seems more responsive, faster and honestly going around corners is a blast... because really I didn't have to use my brakes much on the way home at all. Just absolute glued to the tarmac. I think if you don't push your car very hard (I do) you will find these tyres too sticky/too boring. But pushing my car on Lincolnshire backroads just wow...
Also, wheels are confirmed to be 7.5" on performance pack @Lauren I looked at the rims and they also measured them. Interesting comment from ATS Euro was the 215's although recommended were too stretched on my 7.5" rim and funny enough they recommended the 225, as it would happen I ordered 225 anyway... When he put the 225s on he commented how the sidewalls were straight like they were supposed to be. Whereas on the 215s they were too stretched.
Furthermore, the wheel arches are improved. This is on stock springs, and the wheel gap on the front and back is notably different! Very happy overall, just a small negative that the car is "too sticky" haha. But very happy. I'll give it another very spirited drive tomorrow and give you an update for those that are interested in 225s
