Xray T4 LCG conversion and more...

The only part of the car touching the track is the tyre. You can't magically create (or reduce) weight transfer with some trick suspension geometry.
The geometry affects RC, damping, stiffness, camber gain etc. But the tyre can't tell where you've mounted your links and shocks. It's just a tyre. That car pictured will be made like that for mechanical/layout reasons.

And what difference do you think that makes?

Daleburr is right about how the shock forces are transferred.
About my testing with the arm height, did both front and rear. Already did with both ends with low arms, rear end raised and now both ends raised.

have you tried shimming the rear bulkheads ? Us in IC have tested it and it works really good

hey there is there any new updates on the project ? I’m really interested I’ve just discover some of your other projects just amazed , wish all your designs were mass produce. Cheers

Sorry, nothing new on this topic. Right now Fwd cars take all my energy. The T4 didn't drive for a long time.
The KR-MF has evolved to nearly complete car in the meantime. Little changes and setup work are the daily work. Not very much left to do. Several friends mentioned to build a stainless steel chassis for it. If I could realize that, it will be one of the last things to do.
My guess is, that I will use the T4 outdoor again and then optimize again

You need to consider the weight of a gas car vs electric that's the reason why shocks are mounted more lay down due to weight transfer side to side is more compared to electric.

they angle the shocks because of two things , it gives the shock more leverage on the arm and with more leverage you have to run harder shock/ spring package than you would with convencional geometry therefore resulting in less side to side roll and overall more traction, on TC it has never been implemented because it would overheat the tires quicker ( or maybe not since there’s no roll or weight transfer) but it would interesting to see how a TC with very little roll would perform compare to the likes of the awesomatixs and Xrays.

hmm i wonder where they got the idea from

Hehehe, yeah my friends an I are laughing all day about this coincidence 
I take it as a compliment. Now I just pray the new Xray fwd car is a middle motor chassis with a gearbox like mine (KR-MF)

Of course, with laydown shocks you lose the option to make them 'non-progressive'.
