Heck yea, I just got the Hardcore Racing front shock tower for my storm and it's super good quality. It's machined very precisely and it's tough as nails. Actually, it's probably a lot tougher then nails!
I really couldn't recommend any other shock towers. They take a lot of abuse (especially up front) and if you get the Hardcore Racing Titanium towers you'll probably never have to replace them unless your rig gets run over by a bus.
As a recent Storm RTR owner I would mark the following upgrades as "important":
- Longer bolts for the hinge pin screws. If you can get these, and put locknuts on the ends that will stick through to the top, you won't have problems with the screws loosening up and possibly messing up the chassis. Alternatively, get the Storm Pro or Dynamite replacements, as they are aluminum and a lot tougher. Some people prefer the plastic ones with the nut however, since they will absorb some of the shock of a crash and possibly prevent damage elsewhere.
- Shock Towers. Storm RTR shock towers are unfortunately the biggest slam against this buggy out of the box. Really, replace them asap!
- Hinge pin braces. I got my set from
www.holeshoteng.com and they aren't bad. They will help prevent hinge pin bending and just keep everything nice and tight. You also get the added benefit of not wrecking the front bulkhead everytime you bump into something, since the bumper no longer screws onto it.
Most of the other hopups you can get will just help performance and drivability, although a few are really nice to have like the aforementioned fioroni rear wing brace.
I'd also recommend a screw kit from hexscrews. I have the RCScrewz kit, and although I like the silver screws versus the black ones, they do not appear to be very good! I've bent a few already, and stripped even more. Not good! I plan on getting a hexscrews set soon; most people agree that hexscrews are the best.
It's a great ride if you like hopups! Have fun.
