@Rek so what wheels are you using that wouldn't work? is that cost for the variant 3 or for the version that you bought?KW say that the kit will not fit with my wheel set up at the front so they offered to make a custom set for my car! Fantastic service. A little more expensive and made by their competition team but using road going valving and spring rates.
As for cost, around £2,500 + 20% VAT to HM Government.
