Old new New style front end...

The old style is simplier, lighter and slightly less adjustable, you can still adjust castor, camber, toe, and springs, where as the new style you can also adjust reactive castor and camber in finer amounts (its a turnbuckle instead of a shim).

The new style does provide for slightly more steering but it is really hard and takes alot of time to build one correctly. Everything binds and you cant assume that because you place the castor shims the same on each side that the castor is actually the same, since the molds are off, you sometimes have to put 2 shims behind the arm and one shim behind and one shim infront to have equal castor on both sides, and it can change race to race depending if you hit something... Its really just a pain, and its very easy to have the car start handling really poorly because of the front end, but alot of people dont realize that its the front end making the car handle poorly, not something else.

I have tried both and run the old style front end for both mod and stock.
