Data. Even video of runs compared frame by frame can help if you have notes about what was different about settings and driving. Be careful when looking at bar specs. Rate matters more than thickness or outer diameter. A "smaller" hollow bar with a greater wall thickness may have a higher rate than a bigger bar. It's not always easy to get that info.

I would love to have a little more slalom stability, but I'm just afraid it would be rough in the sweeping turns. I'm glad I have this test tomorrow to play with things. I know that the re-valved Konis that some have been running seem to be much better than the OTS, but I have not driven one with those quite yet. I'll play around this weekend a bit more, but I think a quick change to the stiff setting and going closer to 0 toe will be my first move besides working on the driving. Quote:
Thanks again! I'll report back if I notice anything else. |

I had a lot of time to play with some settings and get some seat time on a couple decent but not great courses at Saturday’s BMW test-n-tune. I’m not sure I’d call my testing process scientific, but I think I learned a few things. It was super dusty and pollen was flying everywhere.
The big takeaways: 1. I seem to be taking sweeping turns too wide. Once I started cutting the wheel more on entry and staying tighter, I dropped 0.5-0.7 seconds. 2. I played with shock settings. I went down ¾ turn in the front from stiff vs. my usual ½ turn from stiff with the ½ turn from soft in the rear and it produced my best times consistently by 0.2-0.4 seconds. I tried even less rebound in the front, but the car got a little wonky. I also tried more rebound in the rear, but that did not solve anything and made things worse. I plan to play with shock settings a little more at future events, though I’ll start ¾ turn from stiff front and ½ turn from soft rear. 3. The car was still not fully confidence inspiring in slaloms. This could be from the nearly corded 192 run Bridgestone tires from 2015, but my quickest runs needed a tap of the brake on slalom entry to stabilize and point the car in the right direction… others didn’t need that. I’ll be on newer tires at the next events, but I think I’ll have to go with a bigger front bar soon enough. 4. I worked hard on rolling steadily onto the throttle mid-corner to exit instead of just mashing the gas, and it’s something I need to remember to keep improving. This might be part of my problem. Thanks again for all the suggestions, I’m going to keep working on set-up this year to get it to work with how I drive. |
