Hi Jilles,

Why have you 2 Camber Angle in the rear and 1.5 in the front? I never saw different Camber Angles on one car!

I have in the front 4.5mm Arm Spacer. What does change if I put 0.5mm more under, to 5.0mm?

In the rear, i drive with the 1XA-1D blocks. What does change if I change to the E-Block. I see very often the E-Block in the rear!

When I change in the rear from 1.5mm to 0.5 Wheelspacer, get I more steering?

Thanks,
Sandro

Hey Jilles,

Great job at the weekend, and thanks for posting the setup, appreciated

A few things I noticed over the standard base, if you wouldn't mind explaining the reasons behind them;

1) Raised front roll centre (0.5 and 1mm shims). I understand the reason for the difference to get the anti dive, but was it a case of trying to reduce the front grip a little? or improve the reaction?

2) 2.5mm lower deck?

3) Shocks in one hole all round. I guess your were looking to slightly numb the initial reaction? This change working in conjunction with the lower deck maybe?

Thanks in advance
Ed

Hey Jilles, congrats for your victory.

Thanks

Jilles,

I noticed with your setups, you always seem to run around 4 or 5mm of spacers under the upper links, while it seems cars in the stock class run around 3mm. Is this mainly due to the roll that is necessary for cars with the faster motors such as 4.5t? or is it a combination of that and driver feel?

Sandro, I'm not Jilles.. but having more camber in the rear gives the car more grip at the end.

Fatal1ty,

On most of my set-ups I always use more camber in rear, better rear traction.
Higher camber link keeps the car more flat and gives smoother cornering.
1XA - 1D is good for stock, in mod you need more toe-in.
When you make the wide more narrow you will increase grip but less stability front and rear.

Ed,
I raised the front to get a smoother feeling in the round corners of the ETS track.
2.5mm chassis works also better on high speed track like this weekend, better cornerspeed.
Marc ran all weekend with his shocks one more in, so I tried it on sunday morning and improved laptimes.

Benoit,
Speedo setting: 2 5 0 0

Carking,
I think it's better with higher camber links. I know from our tests in Bangkok when it was hot that the tyres overheated when using more angle on the camber links and it made the car to aggressive and not smooth to drive.

Tamiya yellow is really soft and also linear spring which I don't like on asphalt, I use normally HB silver.
C blocks make it much more steering as the front is more narrow. If you find this to difficult to drive, try D and B blocks so you get some armsweep. This give less steering into corner but more in the middle of the corner.
Anti-dive also gives more steering into the corner.

Jilles
Thanks Jilles.
Your comment that "Anti-dive also gives more steering into the corner", i always thought it is the other way around.
Saw you ETS setup, where u ran 1c,1c with F0.5mm,R1mm shims. That is anti-dive right? to get more steering? Curious about this though what If the front blocks are lowered to shims F0mm,R0.5mm instead of F0.5mm,R1mm? Will the handling in front be the same?
Thank you!

I'm not Jilles, but I can answer that.
Anti-dive does two things, reduces castor (hence the better initial steering), and reduces weight transfer forward, as the arm takes some of the load.
Given that it reduces the castor angle, it will reduce a little the mid-exit steering though. Its good for heavy breaking though, as the weight doesn't transfer too fast forward.

Lowering the blocks overall gives a lower front roll centre, which should give more front end grip.

Jilles, on that point, would you recomend trying the higher front rc on a big open sweeping track, such as say Halifax? Next national is there in a few weeks time, thinking of things to try and keep the corner speed up.

Regards
Ed

Hi Jilles, I am also wondering why you chose to raise the front RC with the shims under the suspension blocks rather than reducing the ones on the camber link. Is this just personal preference or is there a handling related reason?

Ed, you said that anti-dive reduces castor (thus better initial steering).
but it also reduces weight transfer forward. does it mean decreasing corner-entry steering?? so which one would have greater effect on corner-entry steering? thanks b4.

You get both. The reduced castor gives you better initial steering everywhere (on/off power), while the anti dive keeps the rear planted in big braking zones
