Yeah i got these.. had to fully mould mine in as i've seen others that crack at the joins. Took alot or work. I probably wouldn't bother with these as its only slightly wider, and not as wide as what GTR guards should be.
Anyway cant really see it clearly in these pics, but hope they help. (note: the crome wheels are +20 offset and 10 inch wide rear, while the multispokes are +35offset 9.5 inch rear)
