Yes, from Raceberry:

Although they're not worth the money. I've tried long shocks on the T4 and there's no benefit over the kit shocks.

Forget it, front ones are out of stock and never come back!
For me has benefit since use standard length springs as other cars

I used them to make a custom front bumper brace before the xray part was released. Good quality, no issues and still using it on my car.

Do cars need stiffer springs on asphalt than on carpet?

Id say it really depends on your conditions. High or low traction carpet/asphalt. When I go from small low traction carpet to large high traction asphalt I generally dont have to change much, on asphalt maybe slightly softer springs and more vertical shocks, with less rear toe. But I do run foams on carpet usually, which requires a stiffer suspension than rubber tires. But it really depends on your conditions

Depends how smooth the surface is. Most of the tarmac tracks I race at have a few big bumps. If I go much softer than 2.7 springs the chassis will just deck out all the time, unsettling the car and ruining the chassis.

And generally tarmac tracks are bigger and faster, requiring harder springs to reduce the body roll.

hi guys, just need help on spur/pinion combination:

need to achieve 3.2 - 3.6 FDR with 64pitch

I've got 41 - 46 teeth pinions already but I highly doubt that combining it with 90-86 teeth spur gears would be a good idea. Just by looking at it, i think they wont meet (gap will be big).

any ideal/suggestions?

I have run 92/47 it works but have to file a little on the top deck for the motor to go that far back. A little larger pinion should be possible. So 90/48 or 49 should work I believe.. You'll have to take the top deck of just to change the pinion probably tho.

How can I identify which springs that I have on my car? I bought the car used and I am not sure if it has the stock springs or not. Can I measure the spring wire diameter to determine the rate? How do the aftermarket springs, such as RSD, work?

I ran the car for the first time yesterday. It was on a tight medium bite carpet track with rubber tires. The chassis was dragging on the motor side. I am thinking that a stiffer spring may help, but not sure. The ride height was about 4.8 MM, which may be a little low. Any ideas will be appreciated.

Thanks.

If the springs are OEM Xray springs, they will have the spring rate printed on the top coil of the spring (2.3, 2.5, etc).

It depends on the brand of spring on how they spec them out. Some brands use a number (Xray), some use a color code (RSD I think) and some use a wire size and number of coils (3Racing/Sakura). More coils is a lighter/softer spring.

4.8 isn't too bad of a ride height. I run 5 - 5.2 mm on mine and I still rub the motor in the sweeper at one of the tracks I go to with relatively stiff springs (Xray 2.7). I also run a 1.4 front sway and a 1.3 rear.

Assuming that my car has stock springs, I am not too far off of what you run. Do you run 2.7's front and rear, or the 2.3/2.6's in the rear?

How does Xray shock oil weights compare to Losi shock oil weights? Would Xray 400 be equal to Losi 40WT, or would that be too easy?
