Ran my new t4 14 for the first time today took tq and the win what a great car much better then my old t3 2011. I ran it completely box stock except 4 screws removed from layshaft topdeck, layed in rear shocks all the way thats it ran like a dream 2 laps faster then my t3 almost 18 seconds. My question is what could i changed to make my initial turn in a little faster and consistent. also around our sweeper i had to let off part way thru to keep it from pushing outside. This is on low/medium grip carpet 70x36 track fast lap was 8.01 sec. Thanks guys

More initial, stand up front shocks, 2.6 or 2.7 front springs instead, less rear toe etc

I always run my car with 2.5° rear toe (it's rather 2.75° than 2.5° I think), I like it and it doesn't make the rear loose imo.

To fix the turn-in, go thicker on front shock oil. If you're on kit oil, you may want to go thicker overall, but running the shock oil split will help the initial steering. It sort of acts like a stiffer spring when you first start weight transferring. But it won't cause a mid corner push like a stiffer spring would. Thicker overall will make the car feel more locked-in and precise all over the track.

I'm late to the party but I just finished building my new 14! I'm no pro but coming from someone who has had every single Xray TC from the beginning, this car looks to be the best! The ease of build and the new suspension holders I can't wait for practice this week!!

I have the T4 14 and run Sweeps and Jacos on a "High Bite" track 83X40 and typically don't have traction rolling issues. However when I do, these are my methods to reduce the chances of traction rolling, if I am.
1. Reduce steering Dual Rate and or less aggressive entry "slightly wider entry"
2. Less inner camber link shims (typically 1mm shim at all four)
3. Reduce rear toe and shorten rear wheelbase by 1mm
But all suggestions that have been posted regarding your post I have tried "with other cars" and does help with traction rolling. Once again I feel the solution is all based around your driving style matched against your setup and haven't had an issue with traction rolling the T4 14
But obviously you first want to see if your sidewalls aren't coming un-glued from the wheel (inner and outer).

So last night I went testing with the '14 hoping to get the car to where I felt it could be ultra competitive in 17.5 at some local regional races. I haven't had any time with this car in stock, so I started with essentially a kit setup, and ended up changing these things for the following reasons:
Lower front hinge pins for a car that turns more on the nose of the car rather than using on-power steering to pivot the car round the corner.
Decreased front and rear camber, as I usually run 2 and 2 on the Jacos. Decided to try something different in the interest of again, gaining some off power steering.
Lengthened the camber links to mid front, mid rear to let the car roll smoother into the corner, and to calm it down on exit.
Added some arm sweep to mellow the car through the corner and out.
Lowered the rear camber link on the inner pickup, just for a little bit more side bite to get out of the corner nicely.
Leaned the shocks in front and rear, and added 2mm between the tower and the rear shock. All this in the interest of keeping the car planted, and not too edgy.

Here is the setup I ended with, and attached is the picture of the track I was running on. Medium grip carpet, very very technical. Also managed to set a new track record of 6.094 seconds.
Happy tuning!
