 At what point in handling is a 7" wide rim better than a 5.5", For a street driven car, will I miss that wider contact patch? |

'73 with rebuilt 1.7 that is assumed to be more or less stock, even if it is warmed over a tad bit it is still not a powerhouse of a power plant (IMG:style_emoticons/default/smile.gif)
I have a choice of rims for final build.... 16x7 using one inch spacers (that more or less makes the wheel combo set heavier) (currently has 205's) or 15x5.5, no spacer. (currently has 195's) Both sets need brand new tires and since not a race car and it might see one auto-x a year no need for super sticky tires. So lets say both would get same brand middle of the road tire. I'm thinking the smaller setup would be better right off the bat due to be a lighter combo however would the lateral grip be better with the wider setup? Being a street car and being the responsible person I am, I'd venture to say that I wouldn't ever reach the point of needing the extra lateral grip if that is a something that the one combo would excel at.

I couldn't find sticky tires in stock diameter 15". Just the econobox stuff. So the 16s might be worth it just to get some decent sports car tires.
7s are a tight fit in back, spacers would be pretty thin, depending on camber. My camber is near 0 to get the 225/50-16 7" boxsters 5/16" spacers to not rub the inside. And 215/60-15 on 15x7 944 cookies rub the rolled fender. You might need to mount a used (cheap) tire and trial fit it. |
