So I just bought a 2005 Nissan 350z Manual but it came on raceland coilovers. We have raised them as much as we could but it still somewhat scarpes. Would just switching to stock suspension fox this? My dad insits that we get some cheap coil spacers from ebay which I dont think is a good idea because I havent seen anyone with them. Are there any alternatives to raising the car?

 

Welcome- I've never heard of raceland coilovers, so I have no experience with them. But depending on the OD of the springs being used (and whether the length will fit), you could try running taller springs to gain ride height. But whether you try that or simply get some OEM style suspension, be sure to get a four-wheel alignment when it's done.

 

What's scraping? Tires or suspension? (Presuming tires because suspension components rarely bottom.) What're the size and offset of the wheels? Are there spacers on it? Tire sizes?

 

Do not add coil spacers. There is a reason why you've never seen this done. This isn't a truck.

 

As usual, Mic has good questions. There's also a question about how many miles are on this Z and what the condition of the dampers are. If they are blown, the Z will bottom immediately and rebound only gradually, if at all. Come back and talk with us, OP.

 

At first glance, the tires look too small. What are the sizes? I'd consider shopping around for a decent used set of OEM coils or a Tokico strut and mild drop spring.

 

It looks like a bar in he rear suspension is scraping or exhaust. I dont think its physically the coilovers.

 

The tires are a bit stretched which is how I bought it. I just hope stock suspension would raise it a bit more than it is right now so it wont get stuck. Now I just need to find a set of oem suspension for a decent price lol.

 

put proper tires on there it will raise the car some

 

The Z has 115k miles but I dont think the dampers are necessarily blown. I just think its too low. But my my dad is set on the idea that even with stock suspension it will still scrape so he wants to get the spacers, which I dont trust because theh have no reviews. Do you guys think it will clear if I switch to stock suspension? I still have the spring bucket so it would just bolton.

 

for the love of god... start with tires. you are rolling on rubberbands

 

Thing is I dont just want to waste money for not reason. What if I get new tires and it still doesnt go over?

 

new tires are never a waste of money.. go check the date codes on them

what sizes are they?

if you dont know how to decode, look for the DOT number

 

Well, if there's a bar hanging down that low, suspension tweaks will do nothing for you as putting in OE suspension will indeed raise the car but will not raise the suspension/diff/control arms, etc., just the body height. Still don't know what size tires you're rolling on but I'm with Trav in suggesting tires; as taller tires (if yours are way shorter than the 26.xx" you need) will raise the suspension pieces up.

Suggested tires (assuming the wheels are wide enough):

18s: 245/40F and 275/40R
19s: 245/35F and 275/35R

You should post a pic of what's scraping as well. Only "bar" that goes side to side are sway bars and they're not that low. Only other possibility is some type of chassis stiffener. But my money is on tires too short.

EDIT: Just did a check on those strut/shock spacers. Save those for trucks. What your dad may not have thought about is (no slight intended) are a couple of things.... First, I've only seen listings for "strut spacers" for the FRONT struts. No listings for rear units where the issue is.

And secondly - and more importantly - spacing out your struts will completely screw up the alignment in all settings - caster, camber, toe. Problem is, unless the previous owner installed adjustable front upper control arms AND toe bushings and adjustable camber arms out back, you're SOL as the 33 (and most modern cars) only allow for toe adjustment.

And once again, strut spacers will not raise the suspension parts that are scraping.

 

when exactly does it scrape? is it just constantly as you are driving or only when you go over a bump? is the scraping coming from one side or the other, front, rear?

 

he keeps avoiding direct questions... but hey, his dad knows it all on how to fix it

 

It doesnt scrape when normally driving, just scrapes when going over bumps. Its in the rear area.

 

based on what you've disclosed so far, my best guess is that your wheels are scraping the suspension on the inside. The wheels are probably in need of spacers, not the coilovers. see if you can reach your hand around the inside rim of each back wheel and feel how close it is to the traction arms (on the left in this photo) or the rear upper control arm (top of photo).
you may not need much. I installed Konigs and needed 3mm spacers.

Well not to be automatically against your idea, but I dont think its the wheel scratching against suspension. It leaves metal shavings on the bumps…

 

What are your tire sizes?????????
