Cheers Mike, great to meet you too! And thanks MrB, I've been looking at Funky Power's website.
I think I will leave it to Iain to source/fabricate the correct spacers, as he says that the Eibach ones he stocks don't fit the TSWs because they have a flat back, whereas the Nissan OEM wheels have indents on the rear face.
So as he sells (and uses) the TSWs, he is best placed to source or modify spacers to fit those particular wheels.
When you see the quality of these wheels, it does make others seem grossly overpriced. Unlike a lot of the fancier three piece wheels, the rotary forged TSWs are a tad lighter than the Nissan Rays OEMs, and they allow the correct positioning of the TPMS sensors.
I had a nightmare with custom race wheels for my Z06 when the TPMS sensors would continually break due to not being supported properly inside the wheel.
One other thing about fitting the new wheels, the dreaded clicking sound that was getting really annoying on my car has completely disappeared! Makes the wheels worth buying for that alone.
