K20A Powered McLaren Replicar
I came across this build on the metalmeet forums, and the project has turned out amazing, just thought I would share it incase others haven't seen it yet.

Re: (jdm_dc_fan)
Pretty bad if you ask me. Kind of hard to believe a guy that on top of things still writes "VTECH", calls it a 2.5 liter, and states it has 140hp.
Thing looks pretty nice...he did lose me on the design of the headlights though...something much meaner could've been done.

Re: K20A Powered McLaren Replicar (FUCATYPR)
Im just a little concerned about the rear suspension.... looks like the rear will see a ton of positive camber during compression...exactly the opposite of what you would want !! He needs to move the mounting point for the LCA up a few inches , closer to level at ride height ..

That has been discussed already. Check the unabridged version. He is gonna work on that after he's sorted everything else out.

I fail to see how positive camber isn't desired...because it certainly is. Now granted, I see your point in this situation, as his compression statically appeared as it should at a point of high compression.
Point being, you do want some camber gain as the suspension compresses for cornering ability. For acceleration characteristics you want some anti-squat designed into the suspension mockup, or more optimal placement of the spring assembly to more easily receive the load of the chassis leaning into it, not a decrease in camber gain upon compression.
Personally, I think there is alot to be desired in the design of the suspension on this vehicle. It appears there is an old V8 muscle car mentality at work here that shows within the design. This car will handle well in some ways due to its low weight and low center of gravity, but I suspect the roll couple and instant center will reveal this design ain't so great.
So, to the guy I quoted above, not disagreeing with you, just clarifying that camber gain is what you want, just not to the extent that this particular design will lend.

camber gain in this guys application looks ridiculous, it looks ridiculous with how short that top link is as well as the two hub positions. Give me double A and pushrod/bellcrank suspension any day. Even what he had up front was pretty decent, he could have just done something like that.

Re: K20A Powered McLaren Replicar (jeremydde)
Man, just think what this thing would have cost if the guy had someone else do it. Anyone catch how many hours he has in this? He probably doesn't want to know. Props to anyone that can build ther own car. The most amazing part to me is he used metal for everything! A lesser man would have busted out some fiberglass or carbon for the body.

Typical oldschool domestic kinda guy. I know my grandfather wouldn't have a clue what vtec is, as most older guys probably wouldn't either. "Where's the carb?"

"positive camber" is not what I want during compression!!! negative camber on the other hand wouldnt be such a bad idea, which would easily be attained by moving the LCA up a few inches... the fact that the car is already very low, and doesnt weigh very much, it likely wont have very much compression during cornering so camber by itself wont change drastically... but then when you look at the "rear tie rod" and realize the rear will also have quite a bit of bump steer , and will "turn out" during compression... should be a blast to drive with tons of "over steer", just wont handle "great"
