Tech Adept
Below are the changes(in bold) from the original setup I posted.
Front:
2nd hole from top on shock tower
2.7 Xray spring
300cst oil
4X1.1mm pistons
1.4 Xray bar(short endlinks)
2 degrees camber L/R*Reduced "nervous" feeling during turn-in*
4 degree caster blocks*Less mid corner steering and improved turn-in*
1 degree toe-out
1mm spacer in front/rear of arm
Upper links middle hole on bulkhead
2mm under outer link
2mm under inner link
middle roll center blocks
2mm droop(measuring above ride height)
1.5mm Akerman
1mm bumpsteer
stock servo tie-rod position(upper position on servo saver)
Stock track width(1.5mm spacers)
Stock wheel hex with .5mm shim on each side
Xray diff using Plato as filler
52mm ECS shafts
Rear:
2nd hole from top on shock tower
2.3/2.6 Xray progressive spring *I thought the rear spring was 2.4/2.6 but it was actually 2.3/2.6*
300cst oil
4X1.1mm pistons
1.2 Xray bar(short endlinks and middle position on arm)
2.75 degrees camber L/R
3 degrees toe-in(using 1mm shim at the rear instead of stock .7mm)*Improved overall rear grip*
1mm spacer in front of the rear arm(2mm behind)
Upper links middle hole on bulkhead
4.5mm under outer link
2mm under inner link
high roll center blocks(+.75)
2mm droop(measuring above ride height) *reduced "abrupt" turn-in"
Stock track width
Stock wheel hex
Xray diff w/1000cst *Car turned in better and more stable on power*
50mm stock shafts
Notes:
-Added 1mm(2mm total) between shock tower and front shock
-Added 2mm between the bottom of the rear shock and arm.

Could you please explain to me how you measure droop above rideheight?
I am only used to the other way using a droop gauge.
Thanks

For those that want a comparison between the rear tower on a T3 and the T4;
The only difference betwen the T3'11 and '12 tower is the removal of the QRC holes.

I have always found that grip remains the same but the line between neutral and snap oversteer is much finer. You are relying more on the tire when when reducing roll and this can cause them to overheat in some cases. The main advantage is that the reduction of roll at the rear makes the car transition much quicker and allows the car to "sqaure up" sooner. Again, something these progressive springs do not seem to allow. Hense the reason we are running the shocks stood up and the higher real roll centre. Keep in mind that you can go to far, which is why we need to do more testing.
My T3 11 has a floaty, not locked in feel.
I am running this setup with 2011 L1/L2 inner link mounts in and up front and rear: http://forum.teamxray.com/xform/inde...&setup=t3_2012
BTW, we run Jaco Blues and I use SXT3.0 compound. we can run any low odor compound. Is there a better choice?
