Your car looks great and the steering uprights are a great improvement. What class did you run it in? Would a servo with more torque make any difference?

Thanks MD! I run it in the TT01/TT02 class. We run 540 silvercan or the Tamiya 16T/15.5T sensored motors. Right now I have a Futaba S9551 in there. My TA05v2 that I run in the GT class has the same servo and motor but it is has more steering and is quicker to react. The TA05 has Tamiya yellow springs all around with spool up front and gear diff at the rear, while the TT02 has yellow sprins at the front and blue rear, gear diffs with 1,000,000 oil in the front diff and just grease inside the rear diff

My S is on the kit springs (gold) all round which are softer than the blue (hard) fronts I have on my 05 but both have the same shocks and -1 degree front camber, so maybe go down a grade on your front springs. We're not allowed to run anything other than a kit spec diff though.

The springs on my TT02 are also the short type and not the full length ones. I'll try switching the shocks on both cars next time and see if there's a difference. The front diff on my TT02 is the kit one and the 1,000,000 oil leaks ever so slightly so I may have to switch to putty

How do you find your TT02S handles with the #54651 Upper Arm Mounts compared to the running the top links in the kit position? I've fitted them to the front of mine but haven't had chance to track test it yet and I'm debating whether to put them on the rear also.

I'm a joinin' the TT-02 club! Since who knows what's going on with HPI and the Sport 3's steering system is terrible for my needs, I've chosen the TT-02D Type S kit. I purchased a 190mm Lamborghini Gallardo Super Trofeo body with light buckets off of eBay along with 2 LED kits and a proper wing from Amazon. I have no intentions of using this car for anything other than drifting on less than perfect surfaces and looking sweet while doing it. It may take a couple weeks to round up everything I want to do to it and that doesn't even begin to consider upgrades, of which it will need a few. Not too many, just some basic bulletproofing.

This should be fun. Never had a drift car before. When I want to drift, I just mash the throttle really hard, flick the wheel and I drift. Been doing it that way for many years. Recently I drove a car with hard drift tires and... well... here we are. The third Tamiya kit in my garage and 4th total. My first real RC car was the Hornet some 30 years ago. Now I gotta figure out which car I want to sell. Probably the WR8 3.0. I'm done with nitro.

I know there are other, possibly better equipped drift cars available for less money but those will get mangled where I run and belt driven cars are pretty much useless to me. I need something tough to bash on that doesn't mind the occasional rock getting thrown into the chassis. I don't need a bunch of carbon fiber and aluminum. I just need reliability and fun and Tamiya is pretty good at that.

LiFe Battery

Breyton,

Nice car, that one cost more then a regular TRF. Where did you get the Tamiya LiFe battery from?

Woot! My Gallardo body arrived 4 days early, my LEDs are here and my TT-02D kit is out for delivery. Of course, storms are heading this way but that always happens when I get a new RC car or plane.

Waiting for wing, mirrors and an assortment of wheels to arrive. Still need to sand wheel arches. Front end is way too soft but I haven't done the final suspension tweak yet anyway. This is what I've done so far.

type S

I installed the new Active aluminum front and rear shock towers for my Type-S and it sure looks nice. Replaced the fiberglass units from stock. The fit and finish is high quality, and it took out whatever flex the stock shock towers had. The body posts are now a lot stronger then before. This is my VTA runner so it is not TCS legal but I needed a VTA runner. I also emailed SPEC-R that there was a need to have sealed gear diffs for the TT-02 chassis and he replied that it is a very wise decision to have those parts available and for us to check back in about 2 months time. Can not wait.
