blackstarr- tires are 90% of setup. Run the tires the fast guys are running with the stock setup. You should be good from there. Some changes will need to be made to setup, but most guys or gals are willing to help you get the car hooked up at your local track.

If you are running foams on carpet then you would probably want the original Pro 4 as there will be less chassis flex, if running rubbers then go for the Hara edition.

I'd suggest going with the Hara kit since buying a stiffer upper deck and differential is cheaper than buying the new shocks, motor mount, input shafts, spool, and differential. Not to mention the Hara included the 0 and 2 degree toe blocks which are commonly used on carpet, as well as the delrin outdrives and the new T-nut saving you further investment

Original Pro4 with chassis stiffener is fine for carpet. Maybe not at a big race, but most carpet(the kind I've ran a Pro4 on) probably doesn't have enough traction to slow the car down. You don't really need the delrin diffs, aluminium input shafts, motor mount, shocks or spool. None of those items actually make your car faster, they just look nice over the stock kit parts.

I guess you missed my point. I was trying to point out that, since he had stated that he would want to race the car on asphalt next season, the Hara kit while more expensive includes the parts you would likely want to have and therefore would be the less costly choice between the two.

BTW the new motor mount is much easier to use than the original mount since it allows you to start the screws before the motor is in the car making motor changes faster and easier.

I see what you're saying, but the stock Pro4 is still the best way to be fast and still save money. The stock chassis is fine for carpet, then remove the brace for asphalt. He will have to buy a new diff no matter what. A spool cost 16 bucks. And the motor mount is a luxury, and has no performance advantage.
