Thanks for the kind words guys.
We are not making gear diffs, the one you see in my car is the Spec R diff, modded to fit. We can probably, start selling modded diffs to fit in the cars. Let me see if I can perhaps get the cases machined just enough to fit- it just might be a great product.
What we did have to test yesterday was springs
Our springs, again, not re-inventing the wheel, but they are actually are made to spec for the TC6. What this gives you is a spring that fits the shock body, spring perch and shock collar perfectly, without having to use different spring perches that still make the springs fit poorly (like the Yokomo and XRay ones).
We have 4 spring rates that we tested, and liked the most.
-13.5 lb spring (my favorite at our track for medium-high grip, it really settles the rear of the car down. With the 14.5 the car seemed to float too much, with 12.0 it was way too soft),
-14.5 lb spring (same as the AE Silver- so debating on the need for these, except for the fact that they are made from really high quality spring steel),
-15.5 lb spring (my favorite for the front, really made the car easier to drive more responsive off power and better rear traction on power with the rear gear diff- great for our medium-high grip track)
-16.5 lb spring (slightly softer than the AE Blue, great for high bite, ultra smooth surfaces. Makes the car really stable off power and gives the car tons of on power steering).
The springs really made a difference. They also compliment the shorter links very well. With the shorter links, the car acts slightly stiffer, so we needed something slightly softer "in between" to get the perfect roll stiffness we were looking for. They allowed the car to achieve a balance that I previously was not able to find with other springs. The fitment is perfect and through all our testing they have remained consistent and linear on the bench and on the track. We had another driver test the springs on his TC6 tonight and his results were very, very impressive. He was the only driver to stay inside of a lap of my time in qualifying.
Pictures of the springs are coming over the weekend. Pre-orders for all the parts should be up by Sunday night.
