£2k on rims and I would be looking to buy Japanese wheels - Volk, Advan, Racing Hart, Work etc. I wouldn't spend anything like £2k on Mania's own wheels.
Don't think you can get 20's in them makes? Plus 19's cost around that alone without tyres? Went to ultimate velocity today and got some prices, I'm not after wheelmania alloys as mentioned above a couple of times.
