I want to go to that track so bad, but not willing to risk a 5 hour tow. Do you go to Button Willow?

cossie1600 12-15-2013 02:40 PM

I was at Buttonwillow when one of the club wouldn't let me go to Sonoma due to me being new to that track (I was fine when i went a month later). Buttonwillow is nice, but it doesn't have the "it" factor and it honestly cost me just as much as Sonoma and Laguna once you factor in travel. Also with a baby, dogs and wife at home, I am probably only going to do Sonoma and Laguna only. It's not worth the extra 5 hours I have to drive.

I did put on the rear coilover, took me forever as I wanted to do it right. Setting the height and preload properly took forever. I did take it for a quick spin after. On flat surface, car seems to behave fine. On bumpy road, you can really feel the stiff springs in the back. I hope the fronts are easier to do, I am this close from just calling the shop to have them to do it. Arggg.

$hit. Freaking bolt for the lower front shock froze, I can't change the stupid thing arggg.

Btw, should I get a front sway bar too?

Soak in penetrating oil overnight and get a bigger impact/breaker bar.

When I changed my front stock sway bar links for the SPL's. The stock links was hard to break free. I put a wrench on the link stud and a big breaker bar with 6 point socket on the nut to loosen it. ;)

My front passenger bolt was froze on mine. Beat the hell out of the bolt, soaked overnight with pb blaster and it wouldnt budge. I had to result to a bolt extractor and my neighbor let me borrow his air impact wrench. My 450 ft lb wouldnt get it done but his 900 ft lb made quick work or maybe it was loosened up. Good luck on this task. The nut was $2 at my local dealer.

I went 12k fr and 10k rr spring rate for my setup so curious to what you think once you test out your setup.

I made the mistake of not having a 6 point 19mm. The shop will install the last two at $150

I think you will eventually want one. But I want to say drive the car before you do anymore. Adding more stuff will just confuse you as to what has changed. Try the new springs and ask yourself how it feels on entry, how is it mid corner, what happens when you power down on exit. Don't fix what isn't determined broken yet.

However just based on what guys like Clint and just about what everyone else suggested before, you will probably want to end up running a stiffer front bar. Take your time with it though. You are the ultimate decider on whether it needs one or not.

No one stocks it, I am gonna go with the coilover for now. I probably won't even change the pads, I figure it will be cold

cossie1600 12-17-2013 10:47 PM

I got everything installed. I paid $150 to get the two fronts installed. I am planning to take it into a speedshop to have it cornerweight and realign this Friday. Since I had to rush home after I pick up the car, I was only able to put 6 miles on the suspension. With the front being at 1/3 soft and the back at 2/3 soft, I found the ride to be very comparable to stock. If you rate the stock ride being a 3, this only made it a 2.5 or maybe a 2. The difference is very small. As far as how it drives, I honestly don't have enough miles or hard drives to know what the true difference is. Based on what I could feel, I can tell you to save your $2000 and just invest in a sway bar instead as the car still rolls. The new coilover did make the better in transition, but it didn't really make the car lean much less nor did it dramatically increase its responsiveness. I am going to go back out later tonight to see what I can find, but it's been disappointing so far given the money spent on it. My original goal was to go two seconds faster than my last track day, but I just don't see it happening with the way the car is.

this isnt very scientific, but how much did you lower yourself? for ME, when i went a solid inch lower than stock nismo heights, i felt body roll was reduced a good amount. probably helps that nismo's have stock upgraded sways though

cossie1600 12-18-2013 01:49 AM

Okay back with another update. I took it out for another 6 miles going in circles. I can definitely say that the ride is very good given what it is. I even turned it up to 2/3 in the front, the car didn't ride much worse than stock to be honest.

I did bust out my datalogger and empty the car so I can turn the car a little bit harder than usual. Prior to the coilover, I was carrying an average of .8-.9g through this turn I take everyday. With the coilover, the number jumped to .9-1g at about 45mph. The car still leans, but I would say it leans about 40% less than before. This was done with the fronts at 1/3 from soft, I then did it at 2/3 and my average Gs increased another .5 higher.

I only lower .5 inches

speedfreek 12-18-2013 12:01 PM

Definitely the sway bars eliminate the majority of the lean. That was the most night and day difference suspension wise thus far on my car. With the coilovers working in tandem the car will remain relatively flat. However, I don't have a datalogger to give a percentage. I am hoping to get a track day in early of next year to be able to test the difference with the upgrade to the suspension at Barber.

It's good to hear the increase in performance with these coilovers. Since these get lumped into the all show no go category by some it would be an interesting comparison to see how these performed against say the kw v3's.

GSS138 12-19-2013 10:03 AM

Hey Cossie what did you use as rear rates? Are they true coils or are they shock/spring OEM mounting?

My front set to full stiff did zero!
