EFRA European Championship Setup update!

Prior to this event we already conducted some testing at the warmup race approximately 1 month before, giving us a very solid base to start with. The biggest and most noticeable change I did though was using the long links this event.

1. Long links made the car much calmer, gave more corner speed and was the perfect fit for this track in the SPEC class. To mount these correctly, the most efficient way is to use a large grub screw into the inner top deck screw. Definitely a great setup option for large tracks, which made the gap to the top even smaller.

2. Decreasing the rear caster was also another very beneficial change at this event. Started out with 2, and went back to 0 and eventually landed at 0.8 degrees, which seemed to be the perfect window for the setup we were running. This changed helped the car be less nervous and be much easier to drive, whilst increasing corner speed. Especially on new tires this was a huge help to nail the first and most crucial laps.

3. Increasing the shock Oil from 400 -> 550. After the sun came out on Thursday we increased the thickness of the shocks for TP1. For these hot conditions we had this was definitely the right decision, to increase cornering and keep the car more consistent throughout the run.

4. Hard rear springs for more off power stability. This was an issue I faced with the Hudy tires already at the warmup, which was a quick solve by hardening up the rear, with even more option to stiffen with the shock tower brace which we now have. Additionally, more toe gain is another viable setup option for this issue which we tried around with as well.

5. More camber gain on used tires. In the finals we only had one set of tires, so to generate more front traction we tried to increase front camber gain in order to still have enough front traction and a little less push

6. Rear rocker short ballstud. Another small change to increase rear traction whilst barely taking away front end steering. Taking out the shim and putting in the short ballstud helped a lot and I haven't gone back since the first time I have used it.

7. Upstop travel limit. Another new setup parameter we can finally adjust properly with the SP2 car. Kind of new to using this but we tried a few different settings. On these type of flowing tracks it seems to be a great option to do small tweaks and further improve the car. Furthermore I will have to conduct more testing to further understand and utilize this feature in the future.
