Anker Posted July 26, 2020 Share Posted July 26, 2020 The first run I had a huge spin. At the end of the day I was doing better, but now as well as I would have liked. There were actually two Caterham's on the course. Great to meet Jeff and see his ride. Link to comment Share on other sites More sharing options...
ashyers Posted July 27, 2020 Share Posted July 27, 2020 Anker, Looks like a fun course. Thanks for posting videos. The trick around here is getting registered for the autocross, online registration for the one next week filled up in under 2 minutes! I'm on the wait list with my fingers crossed.

There were actually two Caterham's on the course. Great to meet Jeff and see his ride. Great to meet you (in the real world) also Anker. I saw your times improve as the day went on. I think you still have some seconds to squeeze out with experience driving the Seven. What a blast - huh?! Here's a video of one of my runs, with the sound of a BDA driven in anger (BDA + anger = joy). You can see your car parked when I'm coming in after the run: Link to comment Share on other sites More sharing options...
Black Hole Posted July 28, 2020 Share Posted July 28, 2020 Is that Devens MA? I autocross with the CT Valley Porsche club in a lot in Hartford or the paddock at Lime Rock but that is a much more spacious track than we have. Link to comment Share on other sites More sharing options...
BlueBDA Posted July 28, 2020 Share Posted July 28, 2020 Yes - Devens. Come on up. Autocrosses with various clubs running most Saturdays and Sundays April-October. Link to comment Share on other sites More sharing options...
Anker Posted July 28, 2020 Author Share Posted July 28, 2020 It is one of the best in the country. You will have a blast! The courses laid out can be very fast. On my Porsche Boxster S I have hit the rev limiter in second. Link to comment Share on other sites More sharing options...
Black Hole Posted July 28, 2020 Share Posted July 28, 2020 Its less than 2 hours from my house. Other than the Porsche club who hosts events there? How many cars did they have at the event, how many runs do you get? Link to comment Share on other sites More sharing options...

Anker Posted July 29, 2020 Author Share Posted July 29, 2020 We had 8 runs, which is fewer than normal - caused by having the first socially distanced autocross. Link to comment Share on other sites More sharing options...
Anker Posted July 29, 2020 Author Share Posted July 29, 2020 Basically, there are autocrosses every weekend in summer, both Saturday and Sunday. Link to comment Share on other sites More sharing options...
Anker Posted July 29, 2020 Author Share Posted July 29, 2020 Today I disconnected the rear sway bar so I can see how that changes the way the car drives at the next autocross on Saturday. Will be interesting. Very easy to connect, disconnect and adjust. Link to comment Share on other sites More sharing options...

ahavams Posted September 21, 2020 Share Posted September 21, 2020 Will be interested to hear how it feels sans rear sway bar. Link to comment Share on other sites More sharing options...
Anker Posted September 21, 2020 Author Share Posted September 21, 2020 Mine has a really stiff suspension. The absence of the rear sway bar ensures that both rear wheels stay planted in high G corners. It should induce some understeer, but I haven't noticed.

johncg Posted October 18, 2020 Share Posted October 18, 2020 Anybody want to discuss chassis set up for autocrossing? I just started autocrossing after road racing found my '99 Caterham DeDion had a lot of understeer under autocross conditions. Link to comment Share on other sites More sharing options...

I just started autocrossing after road racing found my '99 Caterham DeDion had a lot of understeer under autocross conditions. Under what conditions does it understeer? Corner entry? Mid corner? Corner exit? What tires are you using? dave Link to comment Share on other sites More sharing options...

I just started autocrossing after road racing found my '99 Caterham DeDion had a lot of understeer under autocross conditions. I find it curious too. Mine has no understeer. It does have snap oversteer on lifting or braking when cornering, but I am learning. Mine is extremely stiff and has adjustable dampers and springs. Because I don't have a LSD is disconnected the rear sway bar to ensure that the rear tires stay planted on the road. Normally that would induce understeer, but not in my case! Also, what rims and tires are you using? I have 13" rims wearing 225/45R13 Toyo R888Rs on all four wheels. Link to comment Share on other sites More sharing options...

I just started autocrossing after road racing found my '99 Caterham DeDion had a lot of understeer under autocross conditions. Hi John Dave's questions are on target since I know he is a superb autocrosser. This is definitely worth exploring - set up, antiroll bars, spring rates, tires, heat, pressures - all essential aspects. Not sure we should hijack Anker's thread but he's a good guy and probably won't mind. However, my first suspicion is that it may not be the car. The clue for me is your recent switch from road racing to autocrossing. When I have switched from road circuit work to autocrossing in one of my Caterhams it takes time to dial me in. Its a different form of driving and you have to be very precise in your steering inputs in time with weight transfer on to the wheel or wheels that need grip. Moving weight around the wheels in a road racing environment is slower than autocrossing - precision is essential in autocrossing for a quick time. My first run (ok...second too.....) usually sees me with bulk understeer caused by me as I do not have the weight sufficiently on the nose. So if you try to flick the car around a cone without the requisite weight on the nose, possibly on part throttle, you will get understeer. I need time to recalibrate myself as a driver. Play your runs back in your mind - is this possibly what you were experiencing? Hope you are not offended by me asking the question.
