I am getting a set of HKS LS+ coilovers installed this week and recently realized I might not be able to park in my parking garage at work because of the speed bumps. Do any of you with dropped Zs notice you are scraping your cars on speed bumps or driveways which you could previously take when at the stock height?

If i end up scraping, im gonna head over to my work on a sunday with a jackhammer and "massage" the speed bumps a little

 

I scrape my stock height z in my apartment complex...

IM moving before I lower mine...

 

Lowered with Eibachs and no additional issues from before lowering, I am just careful in parking spots and if a steep ramp. but otherwise no issues with speedbumps.

 

I've lowered my car to just barely claear a 2x4 on end (3 1/2") . Most speed bumps are ok but there are some high ones out there. Now drive ways are a problem. I had to get driveway plates to span my own driveway and gutters. Steel Plates 16'"wide 48"long 3/4"thick and weigh a ton (didn't want anyone stealing them). Even with 3/4 " the plate flexes a 1/ 4" inch when the car goes on it,

Its eazy to up most steep driveways at a angle it's getting out. Ive got a lip too.
I carry 2 - 2x6x10" pieces of wood in the spare wheel well just in case ( bridging gutters)

 

i haven't scraped at all since lowering the car and adding the body kit, and my car is LOW, probably 4-5" from the ground

 

Look under the car Exhaust flanges are the lowest part of the car. On my car lip sits 5", bumper sides and mud guards sit 4" and exhaust flanges sit at 3 1/2 ins from the ground.

 

My car is lowered with Eibachs. I haven't had problems scraping. I just go really slow on the deep ramps. When I do scrape, it's usually the backside, probably my aftermarket exhaust scraping. I'm getting a body kit soon. I'm probably not installing it after winter. I hope I won't have too much problem.

 

I can barely fit the front of my shoe under my Z. Im so cool!!!

 

I have Eibach, and when I go over high speed bumps in shopping center, it scraps.... I have to go really really slow, then it would be okay. Just need to drive slow when going up driveway, ramps, etc..

 

Im used to going super slow over speed bumps but Ill probably have to go even slower. I hate those impatient minvan drivers that practically touch your bumper behind you while you are going slow over the speed bumps! Damn soccer moms cant be in that much of a hurry!

 

HERES A SOLUTION. I BOUGHT THE TEIN COILOVER KIT WITH THE EDFC. I AM HAVING IT INSTALLED IN ABOUT A MONTH WHEN MY INGS KIT GETS HERE FROM JAPAN. WITH THE EDFC, YOU CAN RAISE AND LOWER THE CAR...EVAN DURING DRIVING.

 

The EDFC adjusts the damping not the height.

Hence the name "Electronic Damping Force Controller"

 

I scraped a couple of times at the end of my driveway. The next time the car was up on a lift I found (as Mr. Twisted pointed out) the the exhaust flange at the bottom of the cats was the lowest point of the car. There are also some points on these flanges, I just had the shop grind the points down a bit and I haven't scraped since.

 

Ditto

 

I just lowered my Z with S-Tune. I'm alright, I can get up my driveway just fine. Actually it feels same stock height.

 

S Tune isnt much of a drop though is it? like 20mm or something?

 

Ditto.

 

You are kidding right? you must have the Tein Hydro Shocks with remote control..

 

hey, sounds like my setup(sittin about maybe...2.5" off the ground) except mines doesn't raises and lower automatically.
