For a mod like this ( and basically any mod), take some time and go thru the entire thread to get a better understanding and several opinions before proceeding. You cut both sides evenly. After install, if you find the need to make any adjustments to a side you can do that. I would recommend starting with 1/2inch cut. If you screw up, you are still left with material to trim to perfection

The process is described on the first page. So, do you have the tools described.? Can you do the cutting. That is all there is. The rest is just putting them back. Otherwise I think there is a guy here that can cut them for you for a fee. Once in a while people sell already cut ones.

i would've done that measurement already except i'm running aggressive wheels so my rims are poking out..i would cut them the same for both sides except i'm hearing/reading stories of ppl having issues with different ride heights on each side...i'm not sure if it's due to uneven cutting or just the way the sides sit...

How is the ride with the Koni yellows? I ask because I installed a set of RS*R Ti2000 springs (.6 inch drop), but still using OEM shocks on my 2004.5. I have 42,000 miles on the car. The ride is a bit too stiff. Can you adjust the Koni shocks to get a bit softer ride? I use my car a lot in the city. The RS*R springs have rates of 345 lbs front and 417 lbs rear. The 2004.r OM springs are 314 lbs front and 427 lbs for the rear.

Yes the Koni yellows are adjustable for compression only, no rebound like you would get with coilovers. I ran on my 350Z Koni yellows with H&R (1.3 &1.0 drop) I do not remember the spring rates, but the ride never was as soft as OEM. Do able though for daily driving with the convience of adjustment for compression with a twist of the wrist for the fronts, backs you would jack up one side and adjust with an allen wrench.
I would suggest doing a search to see if other members have the same combo you are looking at. I personally now have Swift springs on my 370Z with OEM shocks and could not be happier. Still waiting for Koni to come out with a version for the 370Z.

Anyone else having the same problem as me? The picures are gone that were taken to go along with the directions...just would be nice to see them to make sure I'm doing it right.

im running all stock suspension, and finally understand the spring mount mod without the original photos.
i weigh 160 and usually ride alone but dont want to ruin the stock suspension doing this
i hear people experience no issues but they dont specify if they have stock suspension or not.
im looking to bring the back to the same ride height as the front stock *i currently live in N.O. and roads are awful so slamming is not possible*
will i need to do anything down the line if i do this mod?
i was looking at hotchkis springs but if this is cheaper and gives the effect im looking for id rather do this

Like the title says. I get to try the drop and then go back to stock to see if I like it. OR IF I SCRAPE This is with a 3/4 inch drop..
Im dropped on RS*R springs (.6 inch drop - but this about as close to stock as Im going to get. Also riding on 18x9.5 (+20) WORK rims AND A 20MM SPACER )
BEFORE INSTALL
AFTER INSTALL
STOCK VS CUT
Another Stock VS Cut
Sorry for the sh*tty pic - 1 1/4 inch to 1 3/8 - MAY VARY
EDIT***** theres no scraping whatsoever. seems easier to lose the tail end (or perhaps thats just me). You dont lose ride quality - thats for sure. And the looks ......well....pics just dont do it justice.

Just for other people searching up this mod, I used a new spring isolator bushing from Energy Suspension to achieve similar results and cut the install time pretty much in half because there's no cutting involved. The handling seems better, I'm assuming because the polyurethane doesn't compress in a corner like the rubber mounts do.
