I have had a lot of trouble getting aftermarket wheels to clear the Front callipers and my experience is that it is not so much the offset that causes the problem its the shape of the rear of the spokes as they come away from the centre of the back of the wheel.
If the spokes sweep outwards towards the outside of the wheel from the centre you stand a better chance of them clearing.
I am not a fan of spacers so have unfortunately purchased several sets of wheels that would not clear the callipers, I have found that its trial and error.
All I can say is that the wheels I have found do clear are as follows :
OE Enkei Wheels from the Mitsubishi EVO7 which are 8x17 ET38
OE Enkei Wheels from the Mitsubishi EVOX which are 8.5x18 ET38
Enkei Circlar GTA K95 Aftermarket in 9x18 ET42 but the original Enkei Circlar does Not
TSW wheel Unknown model 8x18 ET35
Team Dynamics Pro Race 1.2 in 8x18 ET35 (literally a cigarette paper clearance)
I am pretty sure that the EVO6 and the EVO9 OE wheels would also fit but I don’t have any personal experience of those
