18" alloys...advice needed

[VIL]

Thinking of sizing up from my 17" to 18" alloys (with jspec brakes)

Few questions:

1. will aftermarket 18" wheels bought for an MR2 fit straight on?
2. will i need any spacers of any kind?
3. what size tyres should I be looking for the front and rear?

Cheers

The supra has a wheel pcd of 114.3, hub bore 60.1.

Some MR2's are 100 and others are 114.3.

The requirement of spacers and tyre widths are dependent on the wheel offsets and their width respectively which you haven't specified. :)
