If it gives me too much steering, I can also go back to 3 degrees of rear toe-in.... might do that first.

I wouldn't mess with both rear and front of the car. Increasing rear toe will affect the rotation of the car and mid corner speed rather than just high speed steering. Just my opinion.

Hello fellas! I was hoping I could get some help dialing in some more highspeed steering into my 09. Low speed, and medium speed steering is perfect, the car handles like a dream. But, we have a really highspeed sweeper, and id like to be able to hold full throttle through it with my tekin turbo still engaged, but when I do, the car pushes a bit too much... so id like to do some small tweaking to get more steering, under highspeed.

Ill try to list my setep best I can here:

Track - outdoor medium traction asphault, sprayed with mountain dew
front camber -2
rear camber -2
rear toe in -2
front toe out +1
upper roll center adujustments - lower and inner hole front, lower and outer hole, rear
Ride height 5.2mm front and back
2.8 springs front and back
35 weight oil front and back (I think 3 hole pistons? i forget).

Everywhere but top speed sweaper, the car handles perfectly...

Thanks for any help you can provide, let me know if you need any other measurements off my car.

-cpt.
I would also try 6 degree front castor blocks also maybe more front droop.

aahhhh good idea.. more droop as well, so that while the car is in its maximum on-throttle lean, that inside front wheel maintains contact a bit better.

I will try these and report back after next Sunday's race. Thanks fellas.

Surely if you add more front droop, as the car hits turbo the front will try and lift up reducing front grip

No. Under any given throttle, the front end will lift the same, regardless of how much droop you are running. Weight is lifted off the front tires, and added to the rear tires. Moor droop just means that suspension arm can maintain in contact with the ground longer, before it actually lifts.

In that hard sweeper, what I think is happening, is the inside front wheel is lifting, or is darn close to it.. and the outside tire is overloaded, creating a push. More droop will help keep that inside wheel in contact, keeping the outside wheel from overloading, which SHOULD add traction/steering.

Unless I have that all wrong of course, but that is how I understand it.

Also, a slightly stiffer setting on the front shocks might help as well. My front end is pretty soft.

Hi Guys,

I am wondering if anyone knows what the min & max spur plus pinion combination is.

For example say you had a 75 spur + 35 pinion would equal 110.

So iam trying to figur out what is the min combination total and the max combination total.

Will help me alot as i am about to order some spur and pinions.

Regards

Brad

I thought if you have more droop (front), under acceleration the weight transfer to the back is greater, therefor reducing front traction. Limiting the droop prevents as much of the weight from being transferred to the rear.

i dont think so. If you want to limit weight shift to the rear under acceleration, in efforts to keep on "on power steering"... you want to increase rear anti-squat.

So I ran the 6 degree castor blocks this weekend, and highspeed steering did come up a bit, and it didn't seem to adversly affect the car's handling anywhere else on the track.. so bonus!

Didn't touch droop.

Hi, I have T2 2009 and I want to run front and rear ball diffs.
Problem is, using ball diff up front causes the front belt to rub the
servo saver unit (spring and post) since the pulley is wider than the spool.
Any solution to this?

Thanks

Anyone?

Or is this a design flaw from xray? I think is was corrected to the T3.
Any solution? Or, just leave it like that and wait till the front belt snaps
or create damage to the servo saver...

I have not received mine yet.
Airflow ,does it look like you can gind anything to make it fit?
If it was a design flaw it was a big one.I would have definitly just bought a Tc5.

What can be grinded, that I dont know. I also have a TC5R and it suffers
from this also thats why I bought a spare steering post just in case it got
thin and snapped. The wild movements of the front belt will hit/rub it.
My T2 2009 is brandnew, still waiting for electronics and adding some
stuff like motor guard and batt holder. I dont want to use the front spool
that is included, prefer a ball diff instead. Looks like I have to accept this
flaw. Or use a bigger pulley or tighten the belt to reduce play which I
dont like to do.
