If you want rallye wheels to fit muscle car tires,they are out there in many readily available kits. I designed these to fill a 'niche' I thought I saw in the availability of aftermarket wheels,and tried to fill it. I had a set on a vehicle I had on the contest tables several years ago,and turned down OBSCENE amounts of money for them (grin) There fore,we(RMR/MAS) decided to reproduce them and market them.... In the real world,these wheels are available in up to 20" diameter,and sell well. If these do well,and we see a market for smaller rallye wheels(14"dia. to 18" dia) then we will try to fill that too. but,as I stated before,we felt those were adaquately covered by AMT,Revell,etc.....Steve Zimmerman
