I NEED TO KNOW A COUPLE OF THINGS,YOUR HELP WILL APRECHIATED.
FIRST WHAT ARE THE SMALLEST WHEELS I CAN PUT ON A SRT-10? 17"OR 18" ?

SECOND DOES ANYONE RUN ANY STREET LEGAL DRAG TIRES ??(CHEETER SLICKS)

THANKS

 

There just a few 18" wheels that will clear the brakes. Bogart Wheels in El Cajon, CA made a set of one offs for my friend so he can run Nitto DRs. One consideration on going smaller is that you are lower the effective gear ratio quite a bit. You are going from a 32" diameter to about 27". That may effect performance on the last half of the track requiring another shift and negating at least some of the gains from the improved launch. I'n not saying it's not a good idea, just something to consider. I'll be experimenting a little with these wheels this spring. One other problem that has surfaced with stickier tires is the clutch on the RCs. Once you correct a weak link in the traction department the next weak link usually surfaces. That would be the clutch on RCs. I just upgraded to a Centerforce kit on mine. Of course a lot depends on mods and power output. As you probably know, there aren't a lot of choices in tires for the stock 22" wheels.

 

YOU ARE CORRECT ABOUT THE O/D OF THE WHEEL CHANGING THE TOP END SPECS,BUT IF YOU USE A TALLER TIRE AND KEEP THE TIRE O/D CLOSE THE WHEEL SIZE SHOULDN'T MAKE MUCH DIFFERANCE.KEEP ME IN FORMED ABOUT YOUR PROGRESS WITH THE WHEEL/TIRE COMBO.
SPEAKING ABOUT WEAK LINKS HOW ABOUT THE DRIVE SHAFT AND U-JOINTS? DO THEY HOLD UP UNDER ADDED TORQUE? THANKS FOR YOUR INPUT

 

The last time I checked there were no 18" drag tires with much of a sidewall. I think 50s where the biggest. Those are the ones that give you the 27" diameter. Things may have changed and new stuff may be on the market. If you find something new be sure to let us all know.

I almost forget, the drive shaft and u-joints seem to hold up pretty well so far. But, if the tires and clutch both hook up under a lot of power the u-joints are usually next.

 

I'll trade you my 20"s for your 22"s.... hehe
