The number of dots means size ie 3 dots = 1.3mm, 2 dots 1.2mm.

The team drivers tend to use 1.3mm front and 1.2mm rear on asphalt at events.

My preference on carpark asphalt tracks is to use 1.4mm front and 1.2mm rear.

The thicker front ARB takes away some mid corner steering and prevents the front from hooking in at the apex as you apply the throttle.

Would like input as to what size bars are being used on medium grip parking lot asphalt that is not perfectly smooth, running it in 17.5 TC class. I see the dots on the bars and not sure what sizes they are, currently has the 3 dot bar on the front and the 2 dot bar on the rear. If those are stock bars I may want to increase the size on the front and move the front bar to the rear.

Was running an Associated TC6.2 using one size larger bars on both front and rear than the assembly manual suggested and it was working.

Any input will be helpful, thanks in advance.

As others have mentioned.
A noet of caution, just because that way of tuning a car worked for Associated, doesn't necessarily mean that way tuning will work on the Xray.
But it's always good to have different sized bars as a tuning option.

Also, I don't believe you can put the front sway bar on the back. They are different shapes and sizes. You have to buy bars for the front and back specifically

Forgot about that.
The rear bars have longer 'arms' to reach the front of the rear wishbones where the droplinks are.

Mine had 1.3 on both ends with the 1.2 rear bar as a spare, I put the 1.2 on the rear for now but will be buying a 1.4 & 1.5 front bars.

Thank you to all that commented.

Kit should have come with 1.4 in the front.

It may well have, I'll check with the previous owner/builder and see if he has it. He likes a loose set up so he likely lightened up on the sway bars.

Lighter sway bars generate more traction normally.

New progressive springs just arrived from Reflex Racing, looking forward to testing these outdoors.

I've used the original Reflex springs on a few tracks since the original T4. They've always been great over the bumps and had good corner speed. These new ones are supposed to have more bite as well.

Yellow, Silver and Gold. I have the old yellows and silvers, but the new ones apparently use a different wire so handle differently

My 12 year old used the RSD156 springs on a VBC Wildfire D06 running on carpet and foam tyres at a state title for a 21.5 class.

The car was that good with them he won the state title!

The RSD are progressive yellow, gold and silver in color

Does anyone use the motor guard on their t4? Does it actually help protect the motor? I got hit last week, and my motor can was slightly damaged.
