Bellato, The wheel and tyres sizes you're considering are the same as mine but I'm using Tein coilovers. You will need to be careful on how low you go depending on the tyre that you decide to run as many manufactures have differing measured widths of the same width tyre e.g 285 actual measured width of 295mm. I'm running Nitto Invo's 245 front and 285 rear with the rear tyre being a very tight fit. My car isn't extremely low with a measurement of 631mm from bottom of rim to guard. I've had no issues on the front but the rear I've recently raised up from (621) to the same height as the front (631) due to the tyre scrubbing the guard occasionally during spirited driving. Now that I've done this all is well with no issues. The Nitto 275 tyre is quite a bit skinnier than the 285 (more than 10mm) so if you decide to go 275 you might be able to go lower. Benny.
