Today I tried a lot of things to make the car less exhausting to drive.
I tried anti-roll-bars, springs, shock oil, pistons and axle shims. The track was slower than it was on saturday. I couldn't lap under 11.1s this time. I am not sure why. It seems that the laptimes drop when the outside temperatures drop below 20°C...
I started to prepare the 4WS for the silver TC6 anti roll bars first. I refreshed the shocks, the suspension geometry and the tire loads. With silver anti-roll-bars and a 1000cst/6-hole-piston-shock setup I started the first two runs. The 4WS was easy to control and fun to drive. What I didn't like is the lack of mechanical grip.
The hard copper and red AE-springs didn't harmonize with the silver anti-roll-bars. Soft springs and hard anti-roll-bars always brought an advantage on races, so I tried AE silver all around. The 4WS came to live immediately:
Then I was curious what other oil (400wt) and pistons (3 x 1.15mm) would do. The car felt more connected with the surface, but the overall handling didn't change like the lap time. Around that time I realized that today the track would not allow new fastest laps. The strategy now was to make the car more nice to drive.
Axle shims were next on my list. The car looked awesome fast on the racetrack with 3mm wider track. The lap times didn't change for good
I removed them and put the AE red springs in the rear (silver stayed in front). The car turned better without getting loose. The first 11.1s times of the day. Hard work!
The best change was the black anti-roll-bar in front which made the 4WS more agile and joy to drive.
I will again compare 6° C-hubs to 4° C-hubs next time and make a comparison run against the 6.1WC. What also gives room for tests is the front/rear weight balance. My 6.1WC has a 60/40 balance with more weight in the rear, while the 4WS has an opposite weight balance...
