Is this a problem on the rear left by any chance.
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.

Some more racing tonight at Newbury in the UK.
In practice tried 2.7 rear springs so I had the same at both ends. This did increase initial steering and made the car more aggressive, but it resulted in the rear breaking loose if you weren't smooth (virtually how my T3'12 was)
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

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.

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