Will they look Stupid? Great? Pants? or should I just behave and get the bbk's?

Stick with the BBK's mate.

think the gs has a different offset to the is

Yeah, i think the GS offset is 35. Plus the rears tend to be wider, dunno if that will be a problem for the IS or not though??

offset is 40. Rears are not normally wider than the front however both are wider than the IS 18" wheels so different tyres are required

The 18 x 8.5" 40mm offset GS rims will go on an IS no problem as long as you are not more than about 40mm lower than standard. Mat Clawley's Volk TE37 rims are 8.5" on the rear with 255 tyres and they never rub. I think they are +40mm offset too.

Even the 10" sport rear alloys will go on an IS, there is a guy in Germany with them on his car.

Me? Nah Never!!! Ebay is for loosers

I was under the impression that the standard offset for an IS was 49mm.

I think its 45...

i thought it was 42

OK - Just to clear up the offsets ([url="http://www.lexusownersclub.co.uk/forum/index.php?showtopic=637&"]Taken from here[/url])

FRONT

width | offset | tires range (width)
7 = 40 and up 215-225
7.5 = 42 and up 215-235
8 = 43 and up 215-235
8.5 = 45 and up 215-225

REAR

7 = 40 and up 215-225
7.5 = 40 and up 215-235
8 = 42 and up 215-245
8.5 = 45 and up 225-265 (255-265 requires rolling or having lip)
9 = 49 and up 235-275 (MAY require rolling or shaving lip)
9.5 = 52 and up 245-285 (MAY require rolling or shaving lip, 285 may require more modification)
10 = 45 and up 255-315(requires pulling fender)

so in that case the gs is actually 40 when i thought it was 45.. although in saying that i have just looked at the std gs300 mk1 wheel in my house and it states

16x7.5 jj50

sound like soarer wheels craig!

The list is offsets for the IS

o.k... but what does the jj50 mean?

JJ is the type of rim. I would think 50 is the offset.
