Ok Ive decided if the backordered Eibach Pro System does not ship this month on the 27th as Tire Rack has posted Im going to plan B. That consists of Neuspeed/Koni shocks with a Comptech spring combo.

So can the experts please explain the difference in ride quality, drop, and stiffness between the Comptech springs. The Comptech 110-160(TSX) vs 110-155(TL)? I know from previous posts that either will fit the TSX, but could not find any specific differences.

I'll probably be setting the perches on the Koni's at normal for the rear, and 1 step under normal for the front. Thats what Im planning based on members pictures so far, but that can change to another step lower.

I appreciate any comments or reccomendations.

TsxTuner has 110-160s w/ Neuspeed Konis. Try searching his posts.

I don't have the specific spring rates available at the moment... they're somewhere on this board...

The 110-155 TL springs were originally developed and used for the TSX. They drop the car approximately 1" all around. The general consensus was that the drop was not aggressive enough, so Comptech repackaged them for the TL, and introduced the 110-160 for the TSX. The 110-160 springs are essentially the Eibach Prokit springs. They drop the car about 1.6" in the front, and 1.4" in the rear. The primary difference between these 2 springs is that the 110-155's appear to be linear in design while the 110-160's are progressive. This makes a difference when being paired with the Neuspeed / Koni shocks becuase according to a Koni tech, the Koni's are optimized for use with linear springs. Based on the comments by forum members with this setup, the 110-155 / Neuspeed Koni combination eliminates the wheel gap, provides some improvements in handling, and retains a near-stock quality ride. Maybe try AlterZgo or Caz for their opinions on this setup? For a comparison with the 110-160, I know there have been members with the Eibach Prokit springs and Koni yellows. I'm sure their posts are around if you search for them.

Hope that helps...

Amadeus303 your comments and insight helped alot and thanks for pointing me in the right direction again as far as linear vs progressive. Also thanks for the search tips.

I have the 110-160's. Drop is a good 1.7 F 1.5 R. You need camber kits.
1 finger gap front, 1.5 finger rear.

My fronts are -.8 camber and wearing the inside. I have the SPC F ball
joints not installed yet, might wait for the Skunk2 front control arms.
I have the rear ingalls camber kit and am having alignment trouble, it appears
the rubber bushings compressed at the inner camber link end. I think Im
going to cut off and thread the stock camber link ends and screw them into
the ingalls sleeve. The stock bushing is much stiffer.

I recommend the nuespeed/koni's for the 20mm shorter rod, the 110-160's fit too loose on stock shocks. They even installed without spring compressors onto the 20mm shorter nuespeed/koni ( but that was after they ran some
on stock shocks and settled, brand new they might need some compression to install). Nuespeed also has 2 more spring perch settings.

If I could do it again I might do the 110-155 for the ride quality, but with
spring perches all the way down -.5".

It depends on your roads, I am a bit sensitive to the thumping on hard
bumps. But sometimes I can appreaciate the progressive spring on nice
roads at high speed cornering. To put this in perspective my wife was
complaining about the car bouncing on stock suspension after 18' wheels.
Just from the tires I already needed better shocks. My ride is good now, good
enough that I'm not going to change anything, just mentioning that if
you have terrible roads the 110-155 may be better.

I have the damping turned high at 1 7/8 F, 1 1/4 R for the best ride.
It seams the progressive spring will decelerate compression well enough
and works with light compression damping, but needs maximum rebound
damping, rebounding off the higher spring rate. Increasing the turns on
the koni reduces compression and increases rebound damping which works
well with the 110-160.

TSX Tuner thanks a bunch for your comments and explainations.

So far Im leaning towards the Koni/Neuspeed shocks + Comptech 110-160 just for the looks. So would you rate the ride quality equal to stock ride quality? I read you have 18" rims, same as my new setup. Im wondering if this combo will get me back to a stock quality ride.

I was considering the 110-155 springs, with the Koni/Neuspeed shocks. Then just setting the perches lower on the front to give the Pro-Kit (110-160) looks, not sure if that will adversely affect the handling/braking/performance of the car or not. I figure doing this with the 110-155 springs will not give me an aggressive enough look in the front that I want.

TSXTuner

On the lowest perch ( neuspeed ) the front should be -1.5.
And you could do -1.25 rear to get the raked look with the 110-155's.
Not far from the 110-160 look. If you have AT your front should come
in a bit lower.

My ride is firm and sometimes jittery but less bouncy than stock.
I feel the car dip and then get real hard
suddenly in my seat. This is the increasing spring rate from which you
need high rebound damping.

The worst part is big bumps or undulations at high speed like bridge joints.

It sounds like your more sensitive about ride quality, maybe you should
do the 155's and hope is settles a bit lower. Since I would consider this
might be an indication than I'm looking for a softer ride too.
It depends on your roads, I've been in Cali a long time ago, smooth
as glass compared to what I have.

The next thing I'm doing for the ride is changing from p225 to p235 to get a larger air volume and taller SW, and the ground clearance.

Here's my car with Neuspeed Konis + 110-155s. It's set at the 2nd lowest setting at all 4 corners. I can drop it another 1/4" in the front and/or rear. My car is an AT. As you can see, even with the front and rears set at the same level, the car still rakes forward a bit. I had the rears sitting 1 perch higher before and it raked forward too much. I think this is a more balanced look, but still with a slight forward rake. If you have a 6 speed, the front may be a bit higher than mine as my AT is heavier up front:
