why 2.5"? remove the springs and go -5"

I had H&R springs and spacers and liked it. It was lower than swifts but hard on the oem shocks. Overall no issues whatsoever. I'd also recommend Powertrix spacers hubcentric for a decent price. 140 for a pair of 20 mm and a pair of 25mm. When you lower without spacers, it would look odd with the wheels sunk in. The pix you see below is when I was on H&R's. A good lowering mod with spacers, springs, camber kit and toe bolt will run you between $600 - $650 on the low side. Parts only.

And -- $55.00 for a pair of spacers and you are buying junk. Expect AT LEAST 120.00 or so for a pair. Do not skimp on suspension parts. Duh. They are holding your car up.

I won't argue with you on the camber, you're right, if you want to be 100% in spec, camber arms are necessary.

The spacers though, what's junk about them? My el-cheapo spacers were hub centric, the correct width, had grade 10.9 studs, and fit perfectly. They just didn't have someones name stamped on them to jack the price up.

Currently dropped on Swifts and I don't scrap...often. I still approach speed bumps with caution but most of them I can drive right over without an angled approach. The drop is 1" in front and 1.25" in the rear.

I want to make the switch to coils and lower another 1" in the front and the rear to it will be about 2" drop all around. Will I start scraping my lip, sides, FI exhaust cans all over the place now?

The probability of issues increases with the the cheaper spacers. They may not be all machined the same, fitment might not be the same for all 4, they may crack, etc. Ichiba is the first that comes to mind. It's the same difference between a $15 Auto Zone rotor and a $65 Brembo Blank. They do the same thing, but you're less likely to have issues with one of them.

Z1 has their spacers on sale starting at $88 for 20mm bolt ons. $33/pair additional surely won't break the bank.

i totally agree...mine's stock and i find myself passing-up a lot of parking lots and driveway entrances due to scraping the front end...even some speed bumps cause problems...good luck to you if you lower it...better keep it on a very well-groomed track

Off topic but any recomendations for a cold air intake system? Takeda K&N AEM Stillen?

Caroll smith recommends minimum 2.5" to better 3" of front bump travel, and more in the rear. So assuming you get roll angle adjusters and bump steer correction, and make sure nothing else in the wheel well interferes, then with the 5" or so clearance, you probably can have a max drop of 2" without hurting the performance, and maybe increasing the performance. In order to do that though, roll center adjusters and super stiff springs, and properly matched good shocks are a must.

Swift Spec-R -- $350.00 (or so)

Decent Coli-overs, and I mean decent -- ????

Bilstein are the only coil-overs I would consider and they are $2,100 plus

If the OP needs any of this, he should contact Andrew@NuGen Auto

Spacers give the Z just the finishing touch...I'm a fan of the z1 spacers!
