what are the specs for the rx factory wheels. i've got a sc400 and thought they might actually look alright for rollers.

lug pattern,size etc

 

Which particular year because depending on the year depends on whether the ones you're looking at are the 17 or 18 inch rims.

 

17x6.5 / ET 35 [for the six-spokes]

18x7 / ET 35 [for the hybrid/ 5-spokes]

 

In case you want tyre sizes too:

Standard OEM RX350 - 18x7 +35 5x114.3 - 235/55R18

 

hi guys...

i was looking at some wheel options..

i saw these:

http://www.wheelbasealloys.com/18_In...oy_Wheels__957

which if im not mistaken are 18 x 8j wheels. Will they fit? i don't want to put spacers...

More importantly...will 235/55/r18 fit on these rims?

 

The site says offset between 35 and 42. You'd want an offset lower or equal to what you have at the moment if you're going from 7" to 8". If you end up with a 18x8 +32 you will end up with 13mm less inner clearance... Which may be okay so long as it doesn't hit your rear strut. Profile of the tyre ought to be in the 245/55r18 or 255/55r18 range if you don't want to stretch them over.

They offer test fitting?
