Not naming chassis designers, what type or style of chassis would you build if you were going to design a new car? Do you guys like the 3 bars, 4 bars, swing arms, leafs, etc? I run a big 1/2 mile track mainly and I was looking for some input as we are looking to build a new car for next year. Thanks.

I like leaf cars and feel I could build one and be comfortable enough to make the changes needed to make it fast. But I would like to try a link car but I would have to buy one so I could get the tech support untill I learned what makes 'em go and where the hook up points for the links are placed in the building process. What do you feel comfortable with?

Unimount with corrected front. Would consider newer Metric Impala stub, some consider the best and still not in wide use. Mounts and clearances for rear susp. are great consideration, have read where several board members are strained for room on rear suspension changes.

i personally like the 3 link rear suspension. simple, easy to work with and is hard to adjust yourself the wrong way. either use the fifth arm or torquelink with the 2 link and i also reccomend brake floaters with it as well. more adjustment than leafs and just as easy to work with. coils dont wear out like the leafs do.

I agree with racer4, the last car we bought was a unimount, but I mostly prefer 4-link, myself.

I have to agree with Custom Performance. A 3 link with the option to mount the shocks and springs in as many different locations as imagineable and you still won't tune yourself
out of running decent.

Are there any major drawbacks of going with the 3 link? Is there a point with them that you run out of adjustments and can't get any faster since they're simple, where as the 4 link has a lot more variables? We're building a car from scratch and I was leaning towards the 3 link as well, I just want to make sure I consider everything. Thanks.

the main reason the 3 link is widely used by most manufacturers is it is fast, easy to work with and is very consistent. you can have plenty of adjustment to stay fast for various conditions if built right. like multiple spring and shock mounts, panhard bar behind rear, j bar mounts in front and so on. look under most mods today and the ones that win on a regular basis most likely have a 3 link under them. the main reason a 4 link is not run very much in mods is that most guys dont understand them and what to change when the track changes during the nite. a 3 link you can basically leave the same most of the time and just change shocks or wheel offsets stagger, etc without changing the length or angles of the lower trailing arms, for when the track is changing during the nite.

one more thing make sure you build it with the ability to run plenty of angle in the trailing arms both uphill and downhill.
