I take it that most amatuer car folk believe that larger sway bars are automatically better.

I also heard that with higher spring rates you dont need large sway bars.

Im in the process of buying suspension parts and for now im leaving out the sway bars.

On to the question.

The spring rates on the pro-kit are pretty high, so do i need larger swaybars? Would i need fine just replacing the bushing and endlinks?

a set of 32/21mm or 34/22mm would probably work best with the spring rate of the pro-kit springs, won't ride too harsh and should be right on the money for an everyday driver...you will get lots of opinions on this site, this is just mine. I have a couple buddies with the spring/swaybar combo I mentioned and their cars ride pretty sweet.

typicaly swaybars are used more for fine tuning, while springs make a more drastic change. There is a TON of debate on this subject. Some rather famous car makers (such as Nobel) don't even use sway bars. Others will run HUGE sway bars.

Most of it will come down to personal prefrence. I have had good luck both ways, it comes down to how you want it to feel.

bump..back from the dead for more opinions while i still have money.

i believe stock i have 31/21, correct me if im wrong though.

should i upgrade? or should i leave them stock and just replace the endlinks and bushing?

I would replace your bushings and endlinks now. As Dewey mentioned, sway bars are a fine tuning thing. Keep your eyes peel woe 3rd gen WS6 sway bars. They come up every now and again and can be had for a fraction of what aftermarket units cost. They perform on par or better as well. Lowering springs combined with a few tubular peices, sub frame connectors and a wide set of wheels and tires is enough to make you scared behind the wheel.

Well i have tockico blue shocks, Pro-kit springs, wonder bar, spohn adj. panard, profab lca's and a urethane bushing kit, i believe it has endlinks in it...i havent put it on yet.

I have sfc's but i might sell them(and save ground clearance) and put in a cage as my whole interior is removed...pretty much dryrotted or sunfaded

I have new tires, nothing great but theyre decent....i guess.

Well, I'll just say that with the 36/24 mil combo using polyurethane and and prokit springs my car rides real harsh, but is not prone to nearly any roll. Having every thing in good working order and spohn/Alloy strut mounts helps greatly. I figure I'll move on soon though from the KYB shocks and struts to the bilstein. The KYBs make for a somewhat uncomfortable ride.

I have a prokit with koni yellows, 32/21 bars and poly bushings. Also has 275/17s on all fours. The car is well balanced in the corners and I use it for lap days at road courses. When I was thinking of getting bigger bars most of the people I talked to said that the 32/21s would probably be OK for my set up - they were right; also, when you go up in spring rates you don't need as much bar.

There was a post on here somewhere which had the rates for a Prokit and they were quite a bit higher as I recall.

i had sport lines and 36mm/24mm sway bars and also ran kyb gr2's on my camaro. i was very happy with the way the car rode. it pulled a 1.69 60 foot on dr's! on my gta i have stock front coils with one coil removed(!) and lg motorsports rear springs with kyb gr2's on the front and kyb gas adjust on the rear. i really wish they had gas adjust for the front ,im really happy with the way they perform. i want to try to make an anti roll bar with one of my spare 36mm frontsway bars , and put it on the rear for traction perposes. maybe ill doit this weekend........ultimate cheapo traction aid.

oh btw i really liked the sportline spring, they give a much greater response compared to the pro kit. there much more performance oriented. i think people over look them because of the name. prokit just sounds like more of a performnce spring comared to sport line. nothing could be farther from the truth.

With Spohn subframe connectors you don't lose any ground clearance.


Actually, the Pro-kit has a higher spring rate than the Sportlines. It's not by much but it is higher.

The Players cars came with the 36 hollow front and 24 rear combo but many of the guys swapped the rear out to a smaller bar. Usually a 21 to balance the understeer out. Tire selection is gonna effect this considerably too depending on how wide your rears go and if you are "squared up" or not.

with stiffer sway bars you lose independance between the left and right wheels. so lets say something happens to the front left wheel that is going to affect how much grip the front right wheel can have at times.
with the way sway bars work lets say you are taking a hard right turn.
that will make the body roll to the left. so your front left wheel is being pushed up with the sway bar it tries to combat body roll by in turn trying to lift the front right wheel with it in a way reducing traction to that front right wheel. granted prolly better then before but I would think would be better yet by using stiffer springs instead to help keep each wheel working for itself.


also with sway bars there is no added affect on braking like there would be with spring upgrades being that sway bars work with a lateral rolling of the car not pitch.

if my theory is wrong though someone please let me know I would be thankfull to be informed correct as it has been a while since I have seen what I am talking about so not 100% if I am explaining it correctly

With my 36/24 swaybars + poly bushings and endlinks, stock 183,000 mile WS6 springs and shocks, I have zero body roll, I can hit off ramps at 80 all day long, the car is very predictable. Can't wait till I get the Eibach Pro Kit + Bilstein HD combo.
