if you don't know what do w/ your $$$, go ahead and splurge on the irs. me, i'd opt for a factory team graphite chassis - save the loot and call it a day. unless you are building a collector's item, it's really not worth it. i don't know about you guys, but i race quite a bit, and i feel that cars are disposable. i have raced indoor electric on-road on a regular basis for the past 2 years, and i've gone through 2 FTTC3 and atleast 3 new chassis's. i have been so satisfied w/ this car, that i've become a repeat customer. after a few months of solid racing, nothing can bring your handling back like a new chassis. here's a question for you - when was the last time you saw billy easton, tony phalen, bad-ass baker, or any other team driver use all that hoochie-coochie stuff? you haven't. bottomline - they are team drivers because of their skills, not all that other fluff.
