View Full Version : 17" should I or shouldn't I ?

I have the opportunity to swap over my current SP20 16" alloys to 17" CTW 198 chrome alloys with Kumho Ecsta 205/40/17 tyres (approx 10k tread used so far). The price of the swap over is $500. The chromies look good, no scratches, seem fairly new too.

Going to 17" wheels has me worried about the speedo and extra cost later of changing tyres. Chrome on a Yellow SP20 is ok as I've chromed the fuel cap cover a few months back so it should match the wheels soon.

My question is whether the 17"'s would be worth it? though i will soon be changing federal tyres and that will set me back $480...

I guess I've made my mind up just by writing this email.

Chromies would look sweet man. I'm in the same boat really, just waiting till i need new tyres so I can upgrade. My aim is to somehow obtain RX8 18's from somewhere other than mazda. I spose soon enough some crazy japanese guys will begin to crash/wreck rx8's so the wheels will be easier to come across. But yeh i'd go the 17's if youve got the funds they'd be much better than the 16's.

215/40/17 are the size to keep the speedo right from memory.

goin to stock to 205/40/17 shouldnt pose a problem with speedo.
the speedo would be faster than wot it actually is
if speedo shows 100km/h , u are in fact goin 99.1km/h

just make sure the offset of the 17" are correct...anything higher from +42mm should be ok.....this is for 17x7.
