Hi guys, so my team just finished Sebring and we felt that the suspension needed a bit of work. We have a 1986 nissan 300zx, non-turbo.
I'm trying to get some upgraded shocks for the car and ideally I would like for it to be within the 2X rule.
I saw that according to the rules "The retail price of any NEW replacement wheel, brake caliper, brake rotor (1 or 2 piece), or shock absorber that you put on your ChampCar must be less than twice the cost of a stock replacement wheel, brake caliper, brake rotors, or shock absorber that is available on-line by a nationally recognized auto parts retail chain (i.e. - Napa, AutoZone, O’Reilly, Advanced, etc.)."
My confusion here is that all of those retailers have wildly varying prices and I'm not sure which price to base the 2X rule from. Autozone alone has prices from $55 to $150 for a single strut.
Additionally, what if the parts are not available from those retailers, such as for wheels, should the 2X rule price be based from the manufacturer website?
