So here is a comparison pix between the Eibach Prokit (tops) and Sportlines (bottoms)...it's been about 2 weeks since I installed them, so they are definitely settled --- especially with a trip to Vegas with 4 people, luggage & show gear.







Review:
A !LOT! stiffer. Feel the bumps quite a bit. Not so bad on road noise being transfered, but the ride is nowhere near fat, sloppy, comfy luxury. G35Lin road in it and felt it immediately. Not his cup of Cha, from his expression and statements.

Street Image was doing some work on the car when I borrowed it back do the springs. Eric and Mundo were scratching their heads when I rolled back in. They knew something was different and stated that they liked it even more now that it had been a couple of days out of their sight, but couldn't attribute it to just the wheels that they had put on. Eric was even the one who told me to go lower just the day before. had a good laugh about it.

Thoughts & comments?

 

I like the more aggresive drop. I am too afraid to lower mine that low (daily driver), but I want the Eibachs the most. I think I am going to stick to the S-Techs. I love your sedan, nice clean ride!

 

damn, that is definitely one of the lowest sedans I've seen yet - looks 100x better imo and makes the wheel/tire combo look that much better... what are the spring rates like on the sportlines? hopefully better than the pro-kit...

 

U running 19's bro? 19x9?

 

PHUCKING NICE TED!!!! Sportlines are definitely som good springs. I had them back when i had my old 93 Integra. Enjoy them!

By the way did you change the shocks? Or are you still running Factory? How about the Camber?

 

Chicklet - thanks, a guy always appreciates the props! And my sedan is a daily driver too. I just take it real easy on speed bumps, as well as avoiding driveways with deep gouges or concrete scratches!

bzabodyn -
Prokits are 1.1" drop on the front and 1" in the rear.
The G35 sedan specific Sportline kit is supposed to be 1.6" (Sportlines can run between 1.7 and 2.3" for other cars)

I don't know the exact drop i got, I was stupid and didn't measure! But it's been a couple of weeks and I put a lot of weight on them the first couple of days, so they settled LOW!

05Blk - 19x8.5 front & 19x9.5 rears

Infinite1 I have the Infiniti Sport Tuned Suspension shocks. May be upgrading them, but not sure of the benefit between changing out the Inf.Sport tuned shocks and some aftermarket replacements. I'll be checking into it.

Rear camber is definitely off. As with all new springs you gotta wait for them to settle for aligning...however, I am sure I won't be getting them back into spec without a kit. Not sure which direction I am going just yet, but I will have to very soon!

Cheers, Ted

 

I like the lower ride look...but the ride stiffness might be too much for me.

my coupe's ride height (vs your fender gap) is about your lower height...but
rides only slightly stiffer than stock...

 

How was the ride quality with the Eibach Prokit?

 

I never had a complaint! But I also have Stillen sway bars.... Anytime you get aftermarket springs, you are gonna sacrifice a little ride quality for the drop.

 

Car looks awesome, looks like more then a 1.6" drop to me. But that much of a drop and then your expensive tires, time to invest in front and rear aftermarkt alignment parts, unless you've got a neat sponcer deal for free tires. I guarantee your out of spec enough to be on track for tire wear issue unless you do something.

The aftermarket does make lowering spring option's for the sedan where one can lower the car and not impact ride quality or have very low impact, this is one of the reason's why I publish spring rate charts so member's can make informed choices geared towards what they want out of their lowered car. The aftermarket is far from perfect, their are MANY catches to most choices being offered for the sedan, especially for those of us looking for performance.

Oem sedan sport shocks have a very limited range they can cover if your going with stiffer springs. Even with oem spirngs, Tokico D-specs are vastly superior. They are double adjustable, allowing you to set them to be as firm as oem sedan shocks or a lot firmer. What they bring to the car has NOTHING to do with being into performance, which they can deliver on, it's about superior control that you will not have to search for, just one trip around the block and you will understand why you paid for them. Koni's would also be a better choice, but they do not have the ability to adjust for ride quality. They are single adjustable for rebound only vs the Tokico's double adjustability.

Ted, do you happen to have any pics of the Eibach sportlines? I'd be very interested in seeing the springs themselves.

 

Sweeeet looking sedan.

Thanks for the info... unfortunately, I did not shoot any pixes of the springs before putting them on. If I have a chance, I'll take off a wheel & shoot some pixes. I can actually see them pretty good without removing the tires as the RP03 wheels have a lot of see thru!

I know I need an alignment kit, as I barely got it back into spec with the Pro-Kits. It's almost the next thing I'm gonna install (definitely the next thing to purchase)

And yes, I actually do have a tire sponsor (Dunlop), but don't wanna mistreat their tires so early in the game. Would rather do that on the track, as opposed to being an idiot and running a few thousand miles out of camber.

Cheers, Ted

 

If you have time, can you measure your current fender heights with the sportlines?

 

never measured it with the ProKits, but with the Sportlines the front is about 5" off the ground and 6.5" in the rear.

I measured inside the fender well at the lowest point where my body kit wraps under. Front was measured in front of the tire, rear was measured behind the tire.

Cheers, Ted

 

What's the offset on those wheels? and what size tires?
thanks
