All I can say about the tt-01d is don't waste your money on all of the aluminium & carbon fibre upgrades. I got one off a guy who spent a small fortune who was gutted to find it didn't hold its value. Also had the XB Coppermix Silvia & didn't notice much difference once balanced with added weights. I had no idea how rubbish this model was until I got something much better but are glad I learnt with the Tamiya first.

I haven't had anything break, so I don't see a need for aluminum and cf bits. How bad must I hit a curb for something to break to render a sturdier part? I'm assuming the stock torque motor won't allow the car to go fast enough to do such damage, so this must be for cars with upgraded motors?

Can't say I crashed the brushed car (sport tuned motor) into anything hard enough the foam bumper couldn't cope with. It took a bit of playing with gearing to do the same with a brushless combo. Thankfully it went into the plastic car first as alloy doesn't bend & CF is rather brittle on hard impact. The wife had a Mugen Seiki MBX6 Eco which was an awesome buggy but didn't do well crashing. You're right to stick with the plastic for obvious reason when well versed in common sense like surensm. Save the money for a decent brushless combo & lipo/balance charger that isn't cheap/nasty Chineese rubbish. I started off with that too, thought it was alright - until I invested in something else wisely.

My tt02 hpi mustang body and a mixture of Jaz rider and yeah racing suspension parts

I found it was easy to break the bottom of the front upright when I went brushless.the extension through the lower arm can catch on things.

Let us not forget that this is the tt-02, not the tt-01 thread. Don't want to confuse any newbies that might think some of the tt-01 complaints in here are about the tt-02.

can some one help me? has any one have any idea what the ball bearing is for with the Jazrider brake disc hubs?

Thanx for the feedback. Really appreciate it. Need a new body for my TT clubracer....
Was thinking about the GTR or the concept NSX.
You know how the NSX handles?

Yeah sorry about that, however the comments about the alloy & carbon fibre are just as valid with the new chassis & I'd quite happily have a Tamiya drifter if it was that or nothing. I was just lucky that a friend was getting rid of something better & could afford it at the time. There's plenty of expensive top quality racing chassis on the market so there's always going to be something much better than a tt-01/tt-02 - just to put it correctly into perspective.

@JD Skyline:
I haven't driven the NSX body yet.
My guess is that the Super GT bodies (GT500 class) come out pretty equal in terms of balance and performance. The Lexus RC-F looked pretty much the same in close racing.

About the breaking issues:
The TT-02 is my first plastic car. And so far it appears to be pretty bulletproof. We had some hard crashes when parking-lot-racing and the car took it without damage. In comparison to my T4'15; I wouldn't be sure that the Xray is tougher...

Thanx again for your reply. I definitely will go for the Nissan ahum...the SKYLINE haha...will use it for the Tamiya cup...and club competition.

I have the TT02, but...
I haven't bought any upgrades for my TT02, -other than what I think based on experience w/ other Tamiya kits would be most needed. Aluminum steering upgrade, aluminum motor mount and CV joints for the front axles. Otherwise keeping it stock (but my stock kit came w/ a lot of aluminum and fiber towers, etc... ) -so I think i've spent about $140 total including the kit and will have a pretty nice drive-able basher that shoulld handle quite well. By the way I only purchase upgrades for performance not bling ...

There's nothing better than wiping the smirk off someone's face who has just assumed theirs is better than yours. Especially when I'm running an older chassis to this years.

Hey folks. So I finally have my 02 pretty well sorted out, and with the 17.5 justock and low FDR (thanks again for help there) it's running really nice as a fun time basher.

I went and ordered HPI D compound X tires, and they're great - but - I ordered 0 offset wheels, and evidently the kit wheels are more like 2mm offset (i think).

Lesson learned with my wallet, AGAIN.

I'm going to convert the body to a VTA style, and wheels/tires. I know the VTA bodies are generally 200mm, so once I again I'm worried about buying the wrong stuff. Sorry to ask for another favor, but does anyone know the actual part numbers for a set of HPI wheels and tires that would work offset wise, and be legal for VTA class?

I know they come in different finishes and such, but if someone could provide an example I'm sure I can use it to sort out the choices. I don't want to blow another $40 bucks on the wrong thing.

Thanks again everyone!

If you decide they're not the right fit for your car Tamiya Super Driftech tires are worth trying but any made with ABS are going to be pretty good. If you're running brushless & want something different rubber slicks are a lot of fun. They just don't last as long.
