antheon2010 Posted December 7, 2018 Share Posted December 7, 2018 (edited) Hello Being a sport racer myself i have developed my personal roll centre adjusters and caster plates to aid in the handling characteristics of the under rated toyota chassis. This is what i have came to develep.I can possibly help if any are interested. I also have developed caster adjustment plates. Cheers Edited December 7, 2018 by antheon2010 Quote Link to post Share on other sites
Calum122 Posted December 7, 2018 Share Posted December 7, 2018 That's really interesting. But isn't this designed based off your cars needs. Quote Link to post Share on other sites
antheon2010 Posted December 7, 2018 Author Share Posted December 7, 2018 It depends how much one will go low. The vertical shaft that goes into the knuckle instead of the lca balljoint can be replaced to different length. I do have machined longer ones for more lowered eps.

Calum122 Posted December 7, 2018 Share Posted December 7, 2018 Yeah, I just meant for the average Joe it does require some specialist knowledge? I certainly wouldn't know how to set it all up. Quote Link to post Share on other sites
antheon2010 Posted December 7, 2018 Author Share Posted December 7, 2018 (edited) The lower control arm on a car must never be higher then parallel to the ground. On lowered eps the lca point sky high and as a result starlets do not corner but more over try to turn into a corner as the geometry is not in a good form. It depends on how low the car is. Im finalizing my design and taking various drops to maching various pin lengths. The ideal lca position is to be pointed downwards so it shall be parallel to th ground when the suspension dives such as at a stock height car.

Calum122 Posted December 7, 2018 Share Posted December 7, 2018 Ah that's really interesting. As I say more technical than your average Joe, but not impossible to understand. But I guess it comes back to my original point, the RCA must be made to suit the cars geometry then? Quote Link to post Share on other sites
antheon2010 Posted December 7, 2018 Author Share Posted December 7, 2018 (edited) Yes depending how low you go. Its for people who love more b roads and push it to the limit on tracks. Edited December 7, 2018 by antheon2010 Quote Link to post Share on other sites
morgey Posted December 7, 2018 Share Posted December 7, 2018 Good idea, my concern with a road car would be longevity of it unless you could come up with a suitable boot to put over the rose joint. As for the length you would find a happy medium say that OEM is fine for 0 -30mm drop Then offer length a/b/c for 30-45/45-60/60-75 etc, it would offer a vast improvement in the overall geometry than if you ran the OEM ones. On another note, you could almost use this as a secondary means of camber adjustment too, albeit you would have to undo it to adjust it and it wouldn't be locked up Securely. Maybe a future revision could somehow incorporate that? Quote Link to post Share on other sites
antheon2010 Posted December 8, 2018 Author Share Posted December 8, 2018 Yes you can run a boot if one is considering everyday use. Yes it can be used for added camber but one needs to unbolt it but as as for your doubt that it may not be locked up its machine out of T7 aluminium and have steel timeserts M26x1.5mm to take M20x1.5mm rosejoints. A lefthand / righthand thread would be adequate but in this situation its very limited. Quote Link to post Share on other sites
