B spec Fit comparo in this months C&D is a good read. Though none of the Fit, Mazda, Rio, or Mini really meets specs that closely the Honda kit looks good from here. Fit was fastest ignoring the very overpowered Rio that couldn't meet the intake choke spec. All in all though I suspect letting the Mini in was a shot to the other B spec carsthe Fit will be close competition.
And that kit, costing abot $2k is a serious considerartion for those wanting to upgrade their handling. Shocks, springs, and other goodies have shown theur worth.
Any way its an excellent read.
