You might find that the rear front toe block is not pointing inwards as it should (it twists as the screws are tightened)
I posted about this when I built the car.
You need to hold that block pointing inwards with a spanner or pliers while tightening the screws.

It is the rear. I have assembled the block a couple of times holding both times but I'll try again taking all suggestions on board to see if I can free it up.

Went back to progressive springs.

Next up, more bump steer. I got a former national winning driver to try my car and he said it had lot of initial but lacked mid.
So I added 1mm of bump steer which helped mid corner, added another 1mm for the final so I ended up running 3mm bump steer.

Also tried a gear diff with 2000cSt instead of 1000cSt.

Although the 2000cSt diff didn't appear much faster, 0.02 etc, it did make the car feel more consistent so I was able to stay closer to my fastest laps more often.

So by the end of the evening had kit carpet setup except; 3mm bump steer, 2000cSt in diff and the rear shocks were in the top hole. LTC-R body.

Car felt very good, got my fastest lap to within 0.25s of our 5 times BRCA national champion Chris Grainger's fastest (which is superb by my standards )

Hopefully they'll put the video's up tomorrow so I'll link to it so you can see the results of the changes
Have you tried a different bodyshell to carm the steering down. Best neutral handling shell ive found is the Mazda speed 6.

I started with the Speed 6 last week, but the LTC-R was 0.2s faster per lap

Raced my t4 today for the first time. It felt so good! Rather than being two or three laps down I was only one lap down now if I could learn to drive I could possibly be on the lead lap!

I think this was talked about but I can't find the answer I was looking for. I am guessing the ESC from '12 will work on my T4 when I get it, but what about other brands aside of X-ray make decent ones. Anyone use the spec r? I'm guessing the v2 is better then the older ones I obliterated in my '11. Or do we not even need them with the new car.

Are you talking about ECS driveshafts?

If so I haven't fitted any yet. All the parts I've used are in the kit except for heavier diff oil.

Yes. The ECS not ESC. I had a bout of dyslexia last night. So the stock drives seem to be fine? No chatter or anything.

Hey Cole were you running any ECS shafts or just kit shafts. I wonder if AWD was running kit or ECS. Trying to figure out what to get.

Get the Hudy or Spec R version 2! I only run the Hudy Ecs but always have a spare set handy! Heatshrink the joints to save from a major failure if the set screw comes loose!

Unsettling to see the xray block system is still giving people headaches.
