I somehow don't understands what is going on right now. I like that the stock wheels are 17" and not any bigger. The new Opel Astra for example runs 20" rims, has less than 200 PS and is a heavy boat. What I want for the FT-86 it to put some very light 17" rims, nothing to big or to small, so that ursprung weight will be reduced and and improve handling and performance. I'd look at some Volk, Advan or Enkei rims with Nitto, Toyo or Advan semi-sliks.
The ones I want most are
THESE
The problem is they only are available in 18". I just hope they'll make a set for TOYOBARU specially.
