I'm saving parts from the 4wd conversion to go into another on road. watch for sales too. I buy from a california shop a lot, fg supply. they have some killer sales, just get on the email list of your fav stores. I have KCR springs. All my ordering is done online too, unless I get my stuff at the track... We have an ex hobby shop owner runs once in a while with us and about $2000 worth of tires. He sold me the medium wb mercedes clk gtr. I have a few so can't afford all the expensive bling at once. many parts for the next build re hand me downs hehe
Hobbytek had a sale going, might be worth a look
