The whole concept of setting up roll centre still have me baffled. Adding / removing +1mm shims on inside ball studs affects roll centre but I can never seem to notice the change. Would be great to have a follow up episode to explore this further. Thanks Ray for another very informative video.
It's a complicated subject as the geometry of the suspension also controls camber gain, scrub etc. Depending on feedback from this video it may be a future subject to run through some examples. A 1mm inner stud change should be noticeable as long as the car is in a decent window of setup - if it's outside that window sometimes it can be hard to pick . Maybe send me a pm with your setup and can help in more detail.
@@rmunday76 had the same problem that my setup where way off and after alot of thinking and study of suspension (both Ray and JQ among others) i tested to get a new setup not far from standard (well the guys that constructed the car knows where to set rollcenter etc to function on most tracks) and now i can feel +-1mm or eaven .5mm of adjustment.
Hi Ray from Eldorado in North East Vic. What a great video and thanks for posting. I have a private offroad track here, your welcome anytime. Cheers keep up the great videos!
I watched all of your videos and love them very much! Very clear explanation from the fundamental of physics to drive skill. I very much appreciate and look forward to seeing more courses in the near future.
hey there,great vid!i have a question i race 1/10 nitro car on road,in case of traction roll wht shoud i change first?roll centre? spring?antiroll bar?damping?
Hi mate, it depends on what is causing it. Sometimes it's because the car turns in too fast - in which case lower front roll centre can help. Sometimes its because the rear slides and then the tyres catch and flip, in which case a lower rear roll centre can help. Generally heavier damping will help and stiffer springs will help.
Great understanding and educational skills on physics! Great to see finally someone making these information publicly available. Have been into karting for more then a decade and wished to have an insights into those things back then!
Awesome information. Great explanation 🏎💨💯💪💪👊👊👍👍
Thanks!

Absolutly Great Video! Thanks for sharing this and the support of our great Hobby.
My head hurts, but what each component does, is so much clearer. Thankyou Ray.
Haha it gets easier the more you think about it :)
@@rmunday76 or watch the video several times also makes things get clear and understandable.
Great insight, Ray! Getting confused with roll transfer- what does “high roll transfer” mean?
Update- found the answer 👍
Hey Ray what about shock fluid thickness another tuning opportunity...
The best explanation ever. Thank you so much for this great information !
Thank you!
Thanks Ray, great info and teaching.
Thanks for the feedback!

@@rmunday76 thanx a lot
@@jimjimaco4217 did you test some of the things and how did it work for you?

Thanks for the kind words mate. Glad it has been useful :)
