$49.99 per pair. I actually haven't made any of these in a couple of months as my full time job is VERY demanding. I have the molds 75% complete for the Kyosho 777, Xray XB8, Mugen MBX5, and GS Storm models. I also have a couple of molds for front and rear bumpers to finish. Email [email protected] if interested in purchasing.
I have a set on my Storm Pro, from Hot Products. You can order these from GS Racing - I believe they are listed on the GS site. You can call GS and order parts from them, they're usually responsive and get parts out. You can't order everything GS makes from GS directly but the Medial Pro, Hot Products, and Fioroni stuff you can get no problem.
Anyways they were about $100 and they are lighter then the plastics. It's definately all about the bling factor, and these things will probably crack if I get smacked hard from the side but since I got every other possible storm upgrade I had to get these too =)
They are not pre-drilled and will probably fit most Kyosho Mp7 and HB Lightening Pro buggies. I had to actually dremel a little bit for the pipe stinger because I have the JP-2 with the reinforced stinger.
