Hi there, I'm new
 

I got what I believe is a HPI Sprint 2 Flux RTR , not exactly sure but after extensive research that is what I came up with. I got it from a friend who can't tell me anything about it. I need new wheels and tires, I also want to replace the wheel nuts with purple anodized. But can't find out which ones will fit, M2s, M3s, M4s. and do tires come with foam inserts or do I buy them separate?

Wheel nuts that will fit are m4's ( 4 mm diameter nuts. ) weather the tires come with foams depends on brand and tire. Most racing tires will not come with foams. Unless they are premoumted. Jaco rubber blues work well as all around tires or team Sorex tires too

What you would be better to get is Much More Racing pre-mounted tires. That way you have the tires and inserts. :nod: :tire:

I'm looking for metal Wheel axles, I'm guessing that's what they are called, where the swing shaft inserts into the wheel? Sorry for all the confusion, But It seems like thats the first thing to break on the flux since its brushless and they can't handle the pounding of them... When i figure out how to upload pics that will help my explanations. lol there's still going to be a lot of incorrect naming of parts.

Do you mean wheel hexes? The parts that fit the hex in the wheel and make it spin?
