I tested with ARS for a month last carpet season. I found that although it gave me more adjustment to tailor the feel of the car, it didn't improve lap times. For me, adding tow mid corner was most effective on our typically low grip carpet tracks here. Never had the chance to test on high grip. if I ran on low grip asphalt I'd certainly try ARS again. JMO

This is just my thoughts I havent tested it or anything and I have 0 carpet experience but it makes sense.

The main goal of the ARS is to give more mid corner grip for the rear. More grip=more power or earlier on the power.

On high grip carpet tracks you dont need more grip mid corner. It will only cause unnecessary friction by giving more rear toe in.

On a outdoor track or low traction track you need the grip thus it would be more effective.

That was definitely the worlds, in practice his C hubs were incorrect and the steering arms upside down.
The C hubs were put correct. but in the end he preffered the rack upside down so left it lol.

Hi Skiddins.
What ever Coelho did it seems to me he understand the way ARS works.
On a low grip track the ARS can give you mid corner grip.
On a high bite track with the ARS angled from mid high to the steering blocks low it give the rear a bit of steering and the car is less pushing, result in more corner speed and on throttle more bite thanks to lower front tyre temp.
Try to imagine what the geometry do.
I can not guarantee that you always getting better lap times but this is how it works.

So do you want ARS to increase toe in under compression or reduce it?

Depends on driving style, some like it to add toe, some reduce it, so you'll need to experiment.

I understand what the geometry does with the ARS settings, but there are no hard and fast rules as to when it will make the car faster, or feel better.

For example, Hagberg's starting setup for Austrian ETS had ARS, but they took it off when it became apparent that the grip was strange and too low.

It really is something that you'll just have to test at each track to see if it works.

ARS also requires consistent driving. If you drive 3' deeper into a corner than you did the lap before, it's gonna feel different that lap. This may explain why most seem to prefer the traditional rear suspension.

I'm sure there are instances where ARS is the clear choice. Just seems a little harder to figure that out

I know the short answer is try it and see if it works....

...but have anyone experience with the alu chassis on outdoor asphalt tracks (mod)?

I agree by what you are saying, it differ for everyone.

Default RX4-15 Aluminum

Hi Guys, I know it's not the carpet season, but we've had some good luck running with this chassis even on asphalt.



This chassis is the culmination of 6 months of hard work and testing at our carpet facility. It was the first aluminum chassis project we cut on our cnc router and also the one we spent the most hours on trying different cut outs, flute size and depth, motor pocket width, and different chassis shape.

The chassis initially started life with the RX4 V2 chassis shape and as the project carried on, the shape and features evolved to what we present to you today. The RX4-15 is a labor of love and persistence. Every effort was made to give you the most balanced, versatile chassis for your T4 that is capable of being run with the stock top deck under most conditions.

The result is something we are really proud of. More steering, traction and easier to drive is the most common feedback we get- and we totally agree.

with all the talk about raising the top deck 0.5mm you would think a clever chap like Christan would have develop a shim strip with a tab on the side to hold it while you pop the screws back in,fiddling around with tiny single shims is a pain,how long till we see them in the stores

Yes please, I'd buy some! 0.5mm carbon shims would be spot on.
