I'm looking for inspiration/slap in the face for being silly for my next little project on the trackday 6. I see two problems with my current front suspension setup.
1: The wishbones are pointing upwards since i've lowered it "too much" causing less camber the more the suspension is loaded.
2: Due to maxing the camber setting on the top mounts i believe my driveshafts are a tad to long, it feels like they push on the suspension when cornering (one push per wheel rotation). This could be caused by bumpsteer as well, i'll be looking into that aswell.
I've been looking at some way of rectifying the wishbone angles for a long time but never really got to anything which could be called a good solution (hint, hint, VW stance boys with their roll center kits) until yesterday, when I, in an almost comatose state (due to a man-cold), realized that my previous 307 had front hubs where the ball bearing is screwed into the hub instead of in the wishbone. After a few minutes on the google and servicebox i came to the conclusion that 307 hubs wont work since the shock is mounted differently, however, 406 hubs might do the trick as they seem to have the 50mm shock pinch doodad thingy and upside down bottom ball joint.
My idea is, in short:
Take a 406 hub carrier, replace bearing/hub to suit 306 driveshaft if needed.
Disassemble the 406 ball joint and throw away everything except the threaded part that goes in the hub.
Turn a piece of steel on the lathe to replace the discarded part of the ball joint, but make it a bit fatter and, most importantly, longer.
Weld turned piece of steel into the threaded part of the ball joint.
Take a 306 bottom ball joint and hack the ball section of, in it's place weld in a threaded insert and rod end of suitable dimensions.
Advantages of my idea, if doable:
Suspension geometry it improved, and roll center returns from the depths of hell where it now resides.
Possibility to increase camber by altering new wishbone ball joint length, this would also aid in relieving any excess pressure on the drive shafts.
Things i do not know and would like to find out:
Distance to caliper mounting holes on 306/406 hub carrier from center.
Length of steering arm on the 406 hub carrier
sooooo, any thoughts?
Bonus clip, it already handles quite reasonably, the blue car in the beginning is a BMW M2 with Öhlins suspension on a hot-lap, while i'm on my heat-up lap
