Awesome!! Definitely post some pics ASAP... We want to see them now. LOL

I'm curious, how much drop did you get in the rear. I'm hoping that they don't drop the full 1.3" in the rear, so the car will have a more level look.

 

Got them from SP Engineering in City of Industry. The springs were the same price as Riverside and they install them for much cheaper. Riverside wanted $120/spring to install.
Will take some pics of before and after.

 

Per Spring???

Holy crap!

 

^^Yeah man service is expensive, that's what they charge, I told him straight out what the price on that labor was, some stuff is just worth doing yourself IMHO.

 

What size do we need to use for the isolators?

 

One thing you can do in the rear to gain a little height is what we did with the 1st gen rears with some springs.

Remove the upper spring mount rubber thingy.
& insert a piece of lexan or similar material, max about 3/8" (donut shaped to fit)
then put the rubber mount back.

There used to be a supplier that made these, but I can't find them anymore.

 

Subscribed. Cant wait to see the drops!

 

D@mn, wish I hd know you were looking for one place that would do both. Lou at Amplified Motorsport in Monterey Park quoted me $330 installed, but I wanted to do the install myself and my buddy Rick over @ Riverside had (has, if he's got any left) by far the best price for just the springs... ($225, I think).

 

Thanks man... I like the lexan idea. 3/8" is probably all it will take. I had planned to use the "flat" type Energy Suspension Polyurethane isolators and intall them above the factory upper rubber isolator / bump stop, just like you are talking about. I'll take a better look at it when I have it apart to install the springs and see what will work the best.

Thanks again for the ideas!

Should have the Tanabe's on ths weekend or sometime next week. Just need to find a spare couple of hours to do it. LOL

The isolators should be about 4" - 4-1/4" i.d. an 5-1/4" - 5-1/2" o.d. I won't know what thickness I need to go with until I intall the springs and can measure the drop / gap. I'm guessing maybe a 3/8" thick one would work well.

 

Here is a pic with the spring boosters on the rear. They helped with the saggy bum issue somewhat, but i am not completely satisfied so i am going to try out some rear g35 coupe springs. The boosters seemed to help with my camber issues too.

 

Just another pic with the boosters. I have an extra set of spring boosters so i might see if installing them will lift it a bit more.

 

well I read some guy just put the lowering springs on the front and because of the springs not being the same it messed up his driving dynamics would this happen if you placed spring boosters on the rear?

 

It shouldn't since your spring rates will remain the same. I think the reason that it messed up the dynamics is because of different spring rates.

 

Spring boosters should really effect the driving dynamics of the car, as kejolly mentioned, this is more due to the spring rates being to light or possibly even way too stiff for the car... Th boosters can effectively reduce overall travel, that's why I will be using spring isolators (just like the factory ones, but thicker) instead, if I end up needing them.

 

Thanks again to Rick at Riverside Infiniti for hooking me up with a great deal on these springs!

Just finally got time to install these springs on Saturday.

Overall the install was pretty straight forward.. The rear are SO easy it's not even funny, but the fronts are a little bit of a biatch, though... Took me a little over an hour to do the fronts and about 30 - 45 minutes to do the rears. No special tools are required to do the rear (but you will need a goofloor jack), but you will need a spring compressor tool for the fronts... for both removal of the stock springs AND the install of the new springs.

First impressions.... After only about 200 miles on the car, the car is sitting perfectly level. So far the springs have lowered the car about .80" in the front and .70" in the rear. I doubt the springs have fully settled in, so I plan to check again this weekend, but if this is any idication, I may not need the spring isolators to level the rear, as the springs have actually lowered the car more in the front than in the rear. The springs are ever so slightly stiffer than stock... just cruising you really can't tell any difference, but they did help eliminate the remaining lean (what was left after the Hotchkis sways) when cornering... the car now corners virtually flat, even when pushed to the point of oversteer.

So far I am very happy with them... We'll see if the car is still nice and level after a week or two and I will give an update then.

In the mean time, I will post some before and after pics later today or tonight.
