karman1970 Posted November 15, 2018 Report Share Posted November 15, 2018 Prior to now we have run hard, not sticky tires on our Civic. Dunlop Direzza DZ102s. 460TW. 205/50(or 55)R15s. Don't ask me why. First was on some cheapo steelies, then we upgraded to a set of Integra "snowflakes". Not bad wheels, about 15.5lbs, but kind of skinny. But now we wanna go fast and some conversations on here recently now have the gears in my head turning - which is not always a good thing. I found a couple of nice 15" wheels in the 10-12lbs range, but the wider ones (8-9") all really seem to mess with the offset - some of them move the center line as much as an inch out. How much does reducing the factory negative scrub radius mess with the steering/handling/driveability of a FWD car? Does adding power make those effects worse? I'm really leaning toward welding the diff, but how does that play with a smaller negative scrub radius or even zero scrub? Is there a point where front tires get so big or scrub radius changes enough that you might NOT want a welded diff? Since we're also cheap and may keep our 15x6 wheels for the time-being, what would be the "best" tire size to run on that rim? Narrower tire but "stretched" to fit that rim, the widest thing we can stuff under the fenders, or something in between? Or am I trying to make too many changes at once? Maybe stick with the Integra wheels, a decent 205 or 225 tire, and leave the diff open until we learn how to drive the 200TW tires and extra power? I imagine more grip is suddenly going to change how it stops and turns compared to the harder rubber we've gotten used to. Quote Link to comment Share on other sites More sharing options...
