Re: Lowered cars... improve your ride...
I measured the position of the sway bar mounting bolt at the top of the factory sway bar link to the floor and got 16" and then took out both sway bar links and measured from sway bar mount to the floor again and got 15". That would be with the sway bar just hanging with no loads on it. Yes, I had to crawl under the car to take the measurements. And the links are just inside the wheel line so my measurement was at an angle. But since I took both measurements the same it should be good.
The length of the factory sway bar link when measured from center to center of the mounting bolt holes is 7.8". When I installed my new links I set them to 6 7/8" to achieve the 'neutral' position of the sway bar. Once the new links are installed they will be super easy to adjust. Take off the wheel, loosen the jam nuts, adjust the link and tighten the jam nuts, replace the wheel.
By the way, one FULL turn/revolution of the link will make 0.105"(1/10") change.
I have also added the installation instructions to the FIRST post in this thread..

Re: Lowered cars... improve your ride...
Very nice. I will be ordering a set of adjustable camber arms as well as a set of sway bar links when I am ready for the DIY lowering mod. Great write up and feedback, thanks to all!
Has anyone that has done the DIY lowering needed adjustable camber bolts/plates for the front? If so which ones were used, K-Mac's or the adjustable bolt?
Also the upper rubber grommet on the shock needs to be thinned if cutting the stock springs right?

Re: Lowered cars... improve your ride...
You will probably need to get the adjusment bolts or the Kmac kit for the front after lowering... the bolts are 'adjustment' bolts, not 'adjustable' bolts. They are a fixed amount of a couple of tenths of a degree. If you can afford them, get the Kmac kit. It has poly bushings and eccentric bolts that give you plenty of adjustment. Getting the old bushing out is a PITA according to everyone that has done this. But the change is worth it.
And yes, you should cut the bumpers in the back for lowering so you dont bottom out on the stop. Trimming the front is optional. My Eibach spring kit said to trim the rear bumpers but not the front. Some members have trimmed both.

Ordered!
I will keep you guys posted on how they fair at the Dragon, my girlfriend kindly requested I do anything to lessen the harshness of the 7+ hour ride, so I obliged with more aftermarket goodies.
Think she will believe that the CF hood was purchased to make the ride more comfortable for her?

So the shocks don't appear to be able to use the full travel and absorb those bumps and dips. At least that is what it looks like to me.
When you lower the car the lower control arm moves up. This is what exaggerates the negative camber in back. It also pushes the fixed length sway bar link up, which pushes the sway bay up just like you were cornering. Only it is seeing that load ALL the time, on both sides. Since the sway bar is mounted directly to the chassis, those bumps get transmitted directly to the chassis as well. Could this be part of the reason some of the sway bar mounts are breaking????

Re: Lowered cars... improve your ride...
I have the K&W's on my car and my first impression with the links was WOW! Today I'm supposed to be at the race track but because of a wheel bearing fiasco, I'm spending the day prepping the car for tomorrow. It's a 2 day event, paid in full in advance.
My final measurement on the adjustable links for my car is 7 1/4". Let's see how it goes tomorrow at the track.

Voice up how you like the K-W's and what set up you use for rear camber. I will take some pictures and post up what mine look like. Seems to fit OK as-is with the stocks at my current ride height. Rear tires are wearing on the inside though.

Re: Lowered cars... improve your ride...
Jeremy, the sway bar link install is VERY easy. Plenty of room once you jack it up and take the wheels off. It only takes about 15 mins per side.
Cudaman, the factory camber struts/arms are NOT adjustable. To fix your negative camber you need to get a set of adjustable camber arms or the Kmac kit for the rear.
I measured the factory sway bar links off the car and from center to center of the top and bottom mounting holes they are ~7.8". I adjusted my links to 6 7/8" and installed. I chose this number as I measured the top mounting hole to the ground with the factory links at 16" and with no links installed the sway bar was at 15". I will be interested in seeing how Les does with his set at 7 1/4". Once installed you can adjust them to a different length very easily.

Re: Lowered cars... improve your ride...
Mike, I just got back from my track day and had a personal best by more than 2/10ths of a second. (108.2) When I first went out the car scared me a little because it rolled a bit more than usual and felt different. After adjusting tire pressures I got more comfortable and starting pushing to see what would happen. I like these links but need to experiment with the bar tighter and looser. My first thought is to tighten them because that's what I'm used to. My car was optimized for a tight bar and I left the alignment as it was.
I'm pleased. It means more work to figure out what combination of bar tension and alignment works best but more speed is obviously to be had. I began the day with 3/4 tank of gas, full size battery and no octane booster. My previous best time was with the reserve light on, octane booster in the tank and a 14 lb. battery.
I believe I would have seen a 107.xx if I could have done more consecutive laps. Unfortunately, my car is running hot at the track and I'm just getting into a groove when I have to back off or overheat. Mike, these links are a winner. Now I have some homework to do to get the most out of them. And as stated previously, your car will positively ride much better if your car is lowered by returning the bar to a neutral position with these links.

Re: Lowered cars... improve your ride...
Great feedback Les, thanks for the update. I will be investing in a set along with a pair of adjustable camber arms. It's great to hear some real world experience using the car and your mods to their full potential.
Do you think tightening up the compression rate on your variants will decrease the body roll you feel now with the sway bar link length corrected?
MikeR, thanks for the new options again

The additional roll I felt wasn't much. Taking some stress off the bar resulted in the bar reaching full effectiveness at a higher roll angle. Now I'm going to tighten it back up a hair to see if I can keep the kinder, gentler ride but have the bar working sooner. To sum up, I went from the bar being too tight to too loose for track usage. I didn't take my tools to the track to resist temptation to change the links adjustment before a full test. I'll adjust before the next track day.
Let me point out that on the street all my track observations won't count for much. I never come close to the cornering or braking forces that I reach at the track. I believe these links are going to get good feedback from everyone.
