Im sort of tuning my suspension right now for my 6th gen sedan and I have a few questions....

I have H&R springs they're dark grey...so im not sure if they're oem or sport...what would be nice shocks to match it with? AGX? Illuminas? Koni?

My front sway bar is 26.5mm and rear sway bar is 16mm...I have a strut bar...what thickness for front and back would be pretty neutral?

Would I need to change end links in i change sway bars?

Thank!

 

It is NOT required to change your end-links if you install aftermarket front/rear sway bars.

From what I've seen, most aftermarket sway bars are extremely close in size (+/-1mm) so the differences in strength are negligible. I'm using Eibach Pro anti-sway bars, front and rear, and I am VERY pleased with the car's manerisms. Transient response going into a turn (determined mostly by shocks) is very neutral, but if I quickly pull the wheels into the turn harder, the rear end comes out a bit, but it's far from being 'loose', and is easily correctable being a FWD car.

I'm not familiar with your springs, but FWIW, my setup uses Eibach pro-kit springs, and pro dampers, though my ideal setup would be either Eibach Sportline springs, or Ground Control for coilovers, and definately Koni Yellow adjustables if cash allows.

 

Thickness is not the only thing that determines how stiff a sway bar is. Equally important are such things as wall thickness, hollow vs solid, number and shape of bends, and what material the bar is made from.

My vote is for ST sways. Great quality sway bars and the rear is adjustable, so you can adjust it to your liking.

 

I just slapped on an 04 TL 20 mm rear sway bar ($50 from honda) on my 6th gen (stock otherwise), and the car handles amazingly. During tight high speed turns, I can feel the back end starting to come out, but the car doesn't get sideways at all. All that is needed is a decrease in steering angle (no countersteering). It gives a hint of oversteer when pushed, but during normal driving, it feels very stable, but a lot more responsive than stock. What I'm experiencing is pretty close to what AFAccord said about his Eibach sway bars, maybe a bit more oversteer. I didn't want to get a full set of sway bars for my daily driver, because I don't want it to be super stiff. The TL rear bar was a cheap and effective upgrade while retaining the smooth stock ride quality.
