I think most are using 1". Don't think one is better than the other. Go to Facebook and join 1/5 scale oval racers. Lots of info there.

Yea Im not sure why a fuel tank would make a difference but I was told its not legal .... The quarter scale guys been racing for yrs and use them --- Go figure that rule out .... How about the chassis being legal .... We have carbon fiber chassis & the scorpion chassis on ddm ..... I wonder if those are legal ?

I have a selection of extenders .... You can loosen or tighen your car by moving them around ..... I suggest you buy several and test them .... Ive heard ppl tell me as much as 2 inch but I havnt bought any that long yet .... I think the chassis over all width according to dlmra rules are L-O-L ....1-5LateModelspecs

I don't worry about the RC4Less tires. They will not work on loose dirt which is what we run around here.
