Hi racers,I am thinking of going from 25"tires with 14x6"rims to 22.5"tires on 15x4"rims. My question is the rake will the car act different.We run 1/8 mile arould 6.40s , a Duster with 511/440 I would hate to buy them thin the steering be way off at the big end.Did anyone do close to this?Its to make more room for headers.Right now I have 29.5x10"on back and 25"x6 with the T-bars set low so it has alot of rake now.If I set the T-bars any higher its all over the bigend and hard to drive.~~ Bentwheel43

I really can't say.. Did you have the alinment checked after changing the t-bars ? I went the other way, went from 24in to 27.5 and lowered the t-bars to get the required front end travel I needed and it didn't change the way the car drove at all. 6.20s in the 1/8

C9Thats gonna look goofy. Can you try some Proparts headers?

I have the moog offset bushings about $53 they helped let me lower the front,it drives good.The small tires mite help on reaction time.Maybe~~~

Thanks Cab,I looked it up that 135x15 is 23.62" it mite not look too funny.I saw a (kid) good protree racer useing small GM spare and he was good too!They said the 135x15 works good with 4" rim.
