Generally you'll use the shims when you don't want the topdeck to touch the layshaft bulkheads, this way when the topdeck flexes it does not bind on them. This generates more traction.

I haven't used Arrowmax, but I've used pretty much the entire spectrum of Avid topdecks. With the aluminum chassis on carpet I have found the 1.5mm soft and hard Avid topdecks to be really good on really any grip level. I tried the 2.0mm hard on high bite and it was okay, but I preferred the feel I got from the 1.5 topdecks. Soon I will test the carbon chassis with the Avid 2.0 hard topdeck.

I've tried it a little bit, most recently was the week before our Charity race at JMR. I didn't like it personally, but the track was also a little bumpy then before the re-pave. Europeans seem to like it mostly for high bite, smooth and flowing asphalt tracks.

I also tried it at IIC last year when the car first came out. Alex did as well, we all ended up going back to the standard suspension that week. For carpet I think you'll always want the standard rear suspension.

Tried it twice on low/medium grip tarmac and didn't like it. Even set to 3.2deg toe it had very little rear grip. Probably works okay on RIDE tyres (which understeer a lot) in high traction conditions, but not much use for UK racing.

The PSS inserts are good though, they're worth having. More stability and consistency with minimal loss of steering. Couple of setup changes and you've then got more steering and more consistency = better laptimes.

Are you pairing progressive springs with the PSS like Alex and other Xray drivers are or are you using something else?

I'd highly recommend running at least one boost, it'll take the esc out of blinky mode, and make it smoother. Most ESCs in blinky mode turn into light switches.

I just converted to it. Will give it a try this weekend.

Big track or small track? On a small track, just put in a pinch to smooth it out. On a big track you'll need a ton of boost to have any shot at keeping up with most peoples boosted 4.5t.

With the PSS inserts I've run Xray linear, Xray progressive, and RSD progressive.

The Xray linear springs (2.7) are best if the grip is low, as they seem to give a bit more bite and consistency. RSD progressives (silvers) are great if its hot and the grip is good. I haven't done enough running with the Xray progressives to figure out what their ideal conditions are. At my local track (low/med grip) the Xray linears were faster.

I've only had the PSS shocks for about a month though so more testing will be needed next outdoor season.

Depending on track size, i'd be running boost 90% of the time with a 6.5 (I certainly did when running a 7.5)
If you want to run blinky in mod then a 5.5 for fairly small tracks and a 4.5 for anything larger should do.
The only place you'd lose out not running boosted is the straight.

Can someone explain how changing the arm inserts effects the car, I understand that they change how the arm sits but what do all the different positions mean
Thanks

BY moving the arms outwards or inwards you can alter the width of the car.

by putting angle inwards or outwards you can add or reduce toe in or add toe out

You can alter the roll centre (up or down) if you move the arms level up or down
buy adding an angle up or down you can add anti or pro squat or anti or pro dive

best bet is to download the set up guide for the T4 13 it is basically the same or the Hudy set up guide


you can of course add any combination e.g. to lower the roll centre, add prodive and increase toe in

Does widening or narrowing at the mounting points have the same effect as doing the hex's?

Any news on this? I don't want to get a T4 '15 only for it to be obsolete when they release the T5 in November or December. Are there "sneak peeks" anywhere?

Just tried out the ARS for the first time. At first the rear end seemed to be inconsistent. Sometimes it would loose traction, especially when going through chicanes. Added more rear camber and stood the rear shocks up a bit....really helped it out. The car rotated really well, and I could drive it much harder through the turns. So overall, I think it went pretty well. I used a static rear toe in of 2.5, and 3.0 rear toe in under full suspension compression.
