susspension upgrades

Wanted to know what you guys thought about suspension mods.Which one would you do first?Lower controll arms,tourqe arm,sub frame connrcters,panhard rod,wonder bar,or strut tower brace.I have already rebuilt the whole front end and ive heard Irocs come with something like a wonder bar.Is the aftermarket one any better or should i just stay with the stock one.All my shocks/struts are new and i have mostly all new energy suspension poly bushings.Im thinking of going with the sub frame connecters.What do yall think? SORRY ABOUT THE DOUBLE POST!!!!!!!!!!!!!!!!!!!!!!!

The IROC came with a wonderbar (not something like it). The stock is fine. SFC's are the first real must.

Being new and being good quality are two different things.

A good set of shocks alone would give you better performance quality than bolting on any other combination of goodies. If the shocks aren't good to start with, everything else is basically to put it bluntly a waste of time and money. You have to control the chassis movement.

Wonder bar, I went with the one from Top-Down solutions. They have a diff. design that allows the wonderbar to bolt into the frame as well as the sway bar mounts.

everyone says subframe connectors.. i think they are needed but i ran my car for 3 years now since i bought it without them and always wanted them but had to replace most of the other stuff first. i havent had any problems without them but i think they are next for me...

anyway, i would get a good set of springs and shocks and then a adj panhard bar IF those springs you buy are lowering springs. i would go lowering springs anyway like eibach prokit. they give good handling and ride and only lower a little bit. Panhard bar is necessary as your rear end will shift outward on the driver side as you lower the car

next would be lca's and the brackets to help align the geometry of the suspension. lowering springs throw off the geometry and you'll notice less traction without the relocation brackets. i know i did lose alot of traction with the Prokit so i bought the LCA's and brackets.

also, look into replacing any old worn out bushings. thats a must too.

factory IROC sway bars are pretty good. i havent done them yet. subframes will tighten the car up which will be very helpful. but overall, shocks and springs are the 2 best things you could do. they noticeably make the car handle better and ride nicer, as well as look nicer.

At the time of the new shocks/struts because of money I went with the monroe synsatrac.I know those arent for performance but i couldnt afford the Iroc replacement shocks,I forget what they were called.As for the front end rebuilt I went with all Moog replacement parts.Im sure i still need new springs,but the roads around here con be horrible because the ground is full of clay.So,I dont know if i want to lower it.Even newer cars scrub allthe time and get flats from potholes.You have to replace your shocks/syruts more often than most places here in daily drivers.Being a T-Top car i think i;ll go with the SFC'S first because i've already got creeking Pulling in and out of my driveway,but money is always the decideing factor.
