I know its a really late reply but thanks for the info/ response on my t4 motor mount question 8 )

Hi Skiddins, I grinded a relief recess into my Xray T4 14' motor mount to allow clearance for the rear diff. belt like you said. I wanted to get your opinion on what I am thinking. I saw the 15' motor mount and saw that it only uses one screw hole on the lay shaft bulk head versus the 14' motor mount which uses both and shadows the lay shaft bulk head completely (current belt rubbing issue). Lets say I use my dremel and remove the rear hole section of my 14' motor mount so it mirrors the 15' motor mount design. What you think about that? I know I can make it look pretty minus the aluminum finish missing all that wonderful orange anodized aluminum. You think that will decrease my chances of tweak in that area as well? I know you had the same issue as I did and wanted your take/ opinion on all this. Thanks in advance and my car is setup for 17.5 TC.

Good to know, cheers.

What size holes/oil are you generally running in the pistons on the T-shox as a baseline?

I've started with 3x1.4mm and 40W AE oil and the damping feels pretty light. Yet to test.

Also ordered the CSO short springs, 2.4nm, 2.5nm, 2.6nm and 2.7nm as the AME green and blue shocks are approx 2.8nm and 2.9nm so I should have a good range.

Hi there, as it was off topic from the T-Shox thread I thought I would drop you a PM, I hope that's okay. I usually stiffen the springs when changing from tarmac to carpet to improve response and limit roll to prevent traction roll among other changes. But generally all changes are to stiffen the car is this wrong? I know it depends on driving style but softer seems to fly in the face of everything I had learned (or thought I had ).

Most carpet chassis seem to be stiffer, thicker roll bars are used and I thought stiffer springs?

How have you been getting on with the T-Shox? have you found the need for harder springs than the AME blue? Also have you drilled the pistons to 1.4mm or are they stock 1.1mm?

Sorry for all the questions

While the Tamiya's always seem to be very fast in top drivers hands, the Xray's seem to be easier to drive for everyone else. The latest version of the Xray seems to be even faster again and will be as competitive as the Tamiya. It soubnds like everything is fairly even for you, but the Xray will be more reliable.
You should probably base your choice on which car can you get the most help with setups for your class, the Xray always has a lot of people willing to help, here on RCTech and on Xrays forum.
