I am doing the research right now on the Brit sites trying to see all the combinations of rims, tires, and progressive rate springs needed to make the Smart behave better when pushed a little (ok more then a little ;))
Any one else doing the same....perhaps we need to share info
I find much of the info on
www.onsmart.co.uk/ to be well worth sifting through
Along with all the good advice from the main folks at
www.smartmania.co.uk/
