So true but sadly people still buy them under the impression they make the car stronger. Give me good old plastic any day of the week.

Super glue on the outside front tire sidewall or the on the outside edge of the front tread. Try it with some old tires first

Hello All,
Been awhile since I last ran the TT02 as well as posted, the late part of the summer got a little crazy and I lost one of my best friends to cancer a couple weeks ago.....That was rough as he was my first contemporary that I have lost but he is in a better place.
With that said I spent some time with the TT02 this week. I gave the chassis a good cleaning (it was filthy and was causing some sticking in suspension arms) and refilled the shocks, the CVA's had leaked enough that the pistons were sucking air at full stroke. I also got a set of the Tamiya short TC springs. On my make shift track (dusty tennis court using field markers) I feel like I am battling some heavy oversteer. I think on turn exit I was just being a little ham fisted with the throttle but I also had oversteer during steady throttle sweepers and under braking. I was running the standard silver springs from the friction shocks on the front and the stock springs that come with the Super Mini CVA's (Yellow I believe) on the rear. I have not run it yet but I have gone with the red (soft) in the rear and blue (stiff) in the front. Both sets of springs are softer than what I had in there, the yellow spring that were include in teh TC spring kit feel softer than the yellow springs that came with the shocks but I may be wrong there. I hope to get a pack or two in tonight to see if it made any difference. If that does not work I will address the shocks and go softer in the rear, right now I am running the two hole pistons with 40wt oil.
Now that the little man is back in school my schedule has eased up a lot so the car should see a lot more running time.
Cheers,
Jim

Alright...I ran a half a pack through the TT02 last night, a couple came and wanted to play tennis :-(. I have to say that there has been a noticeable improvement in stability in the sweeper.
It is also funny after not running it for a few weeks how my brain/finger was more receptive to trying different driving styles. In the past I seemed to be using the "fast into the corner" mentality which usually meant I would have to coast or lift mid turn which of course unsettles the chassis. Last night I was showing some restraint with corner entry speed which allowed me to power through the corner which made a world of difference.....actually at times this technique resulted in understeer which I have not really experienced before.
Last night I downloaded an app called RC Timing. I played around with in the house and it seems to work. It uses the camera to detect color differences and even through it says that white is a hard color to pick up it seemed to work. I am hoping to get to use it for real tonight and will report back. This will be awesome for someone like me who likes to do hot laps but does not have easy access to a track with a timing system.

Jim

I had an hour free time last night and I started playing with my TT02 again. I was going to try playing with droop by using some spare o-rings in the shocks but as I am looking at it I decided to put the car in "normal" ride height mode. When I built the car I assembled it in "high" ride height mode but these days I am doing 99% of my running at the tennis courts which are pretty smooth.
One thing that always bothered me about my TT02 was the fact that there was a significant amount of bump steer as the suspension compressed, I tried shimming the balls on the hubs but I just could not get rid of it to any great extent. In static I set it up to have a wee bit of toe-out but as the suspension compressed I would get significant toe-in. After changing to the normal height setting that is all but gone.
Just as I was finishing up we had a very heavy sun shower and when I got to the courts there was significant puddling so I did not get to run it yet but I am excited to see how she goes with a 7-8MM ride height, lower roll center and not so wonky bump steer.

I was out seeing customers this morning and on the way home had to stop by Ikea to pick up some fixtures for an upcoming trade show. I was taking care of a few e-mails in the back of the parking lot when I remembered I had the TT02 in the back of the car from last night so I thought I would give it a go. The parking lot asphalt is only a couple years old, sealed and in very decent shape.
I set it down and take off......it is a VERY different car and I mean that in a good way. It is so much more stable on big sweepers, it did not feel like the back end was going to swing wide any moment. I did loose a bunch of initial turn in but mid turn and turn exit felt pretty good. Obviously I am on a different surface than what I am use to but I am thinking that going to the lower suspension setting has made a huge change in how the car handles. Once I get to run at the tennis courts I will let you guys know how she does.

That is kind of cool in a weird way. With that said it just would not work for me, I run on a tennis court and between the dust on the surface and tires my car gets filthy after just one pack. At least the black hides the dirt somewhat.

I'm run the white hardened tub and even on carpet it gets dirty.. mine has black marks underneath from traction compound / runner residue. I wipe it clean frequently but it doesn't all go away.

I ran mine once and it is already dirty. Kind of expected with the white though. It's a performance upgrade, not an ascetic one though, so I can live with it.
I've found my Type R to be very tail happy, both when decelerating and accelerating - far worse even than my XV. Did some spring and shock tuning last time out to no avail...finally noticed my rear axles have a ton of lateral slop - not sure how I missed it to this point. I added shims on the axle to tighten things up - hopefully this does the trick. We'll find out tomorrow.
