ive always loved the way euro-touring cars looked. slammed, stock fenders, and lifting a wheel...

correct me if im wrong, but when a double-a arm suspension is in load it has little to no effect on alignment like camber, etc. unlike the mcphearson setups or the multi-link setups... sooo wouldnt he be right?

just my thoughts...

 

Good answer.....

A double a-arm is much easier to set up when the car is lowered plus and is more adjustable. In general the lower you go, the further out you go to keep the lower arm as parallel as possible. You dont have the same constraints as a macpherson strut, or a 5 link. As long as you keep the lower arm parallel with the ground you are in good shape. Also the biggest problem with 5 link is binding and the arms working against each other.

Only problem is Double a-arm set ups is they are really only on open wheel cars or custom racing cars. There are practically no road going cars with double a-arm suspension, unless you look into ariel atoms and other such small car manufactures.

 

There are few road going cars with double wishbone because mac pherson is cheaper to make. That is why the econo s-chassis cars got mac pherson, the the creme of the crop (r32+, z32) got double a-arm.

 

Not quite sure what u mean by "in load". But double a-arm allows for progressive camber changes, and allows you to tune roll center. both of which mac pherson do not. When you lower a mac pherson equipped car, the roll center falls at a faster rate than the center of gravity, increasing the roll moment which cause the car to lean more in the turns.

Mac pherson = bad for performance.

 

Its not bad, its just harder to work with. You have to raise your roll center the lower you go.

Its just more of a pain in the ass. But it does have a larger increase in camber gain then most would want under compression. Its useable up to a degree. But most racing set ups ditch it for the ease and adjustablity of an A-Arm set up.

I posted up a Double A-Arm rear suspension conversion for 240s like 2-3 weeks ago. Its 8k from japanland. Its an entire subframe and link set-up. Its bad ass. Then all you have to do is convert the front to double wish bone from a skyline or custom a-arm and your set for ultimate grip.

 

BTCC has the best fucking crashes....fuck nascar!

 

holy crap. 8 grand... really... and here I was just about to ask what all it would take to convert...

does it really take all that much?

I'm just beginning to break into the vast world of suspension, so please forgive the ignorance...

 

Its an entire rear suspension unit that replaces everything except the shocks and brakes.

cool
thanks, I'll check it out

wish the price tag wasn't so high, though, I kinda get it as to why
