I have a set of silver Turbo Dynamic wheels for sale, with tyres on.
Fronts = 16" x 7.0J rims, ET35 offset. Toyo Proxes tyres: 205 x 50% with loads of tread (approx 7mm).
Rears = 18" x 8.5J rims, ET15 offset. Federal RSR tyres: 245 x 35% on the legal limit of tread (approx 1mm on inside edge, 4mm on outside edge).
Squeezing the rears in may require you to increase your rear camber, it's impossible for me to check on my own car as it's arches are modified and these wheels fit with ease.
£450 for the set.
