I have a 95 Q45 that I'm in the process of fixing-up.

I've purchased 300zx turbo calipers..

I'm looking for some good solid advice on loowering the Q45 with 300ZXparts.

I've read the VIP and the Q45 forums.... still not clear on what works the best.

Brands KYB,Tokico etc...

I also want to run 350Z disc brake and I was thinking 18" or 19" wheels.

If I could get the Q45 Experts to put there $.02 cents in...

I'd greatly appreciate it.

Want to do something soon, while I have the $$$

thx,

Before you get started, has all other maint. been done? KS's, valve covers, under plenum job, plugs, injectors-harnesses, belts, pulleys, fluids, O2's, get the picture?If she doesn't run well why waste your hard earned cash?

The free length of the front springs is ~ 16" the body weight compresses the spring to 8" and the net is 6.7" before binding.

Most shock absorbers are designed for a 7" max stroke. Rubber bushings are added to protect them so normal designs have a +- 3-3.25" dynamic range.

Please explain how you will lower it and yet retain full suspension travel.

What is your goal? Static visuals or dyanamic performance?

Thanks for the question

I'm leaning for the performance for the Suspension....

But, I really like the Look of "the Japino" Q.

I'm also thinking about 18" wheels staggered ..rather than 19".

I want to try to avoid scraping and bottoming out on hard turns etc...

So, I'm I going to use the Q45 Spindle or buy Z32 spindles ??

Also, Is there any pic's of "Wes" set-up posted that haven't expired ??

Looking for a nice handling, semi-good riding, Lower Q45.

Thx,

This is a good question, so we can understand the "intended" goal.

Bit sure he can answer the others??? He's "wanting to", he didn't say he's going to.

Thanks for the reply

My intented goal is to have a Nice "lowered" look and stance.

Also, a More "performance road feel" with the suspension

I have 300ZX Turbp Brake Caliper...front and Rear.

Leaning towards 18' wheels staggered.

I'm thinking I could get the desired Look and Feel with a 300ZX set-up.

So, If someone has done this.... I would like to hear from you.

Maybe the Best Struts/ shock combo.

Would stock 300Zx parts work or go with SPL parts ??

I know about 350Z front rotors ...what about the Back of the Q45 ??

Up front 300Zx or Q45 Spindle ??

If any of the Q45 experts could chime in...

I'd appreciate it.

regards,

The problem with redesigning a suspension is where do you attach both ends................of the dozens of suspension arms, coils, and shocks........................a 3 dimensional problem.

Not knowing that the sole purpose of a suspension is to control and compensate for tire changes leaves one lacking!

I guess if the "japino or Wes could maybe give their thoughs on the 300ZX

parts and what they used.....

I think that might clear things up for me.

Also, if the would have any part number and or Pictures of their 300ZX suspension on their Q45.....

That would be great.

Well, none of these problems exist with stock.

If you really want to look lower (very minmal performance gain) and want to buy all the additional parts so you can align your suspension to OEM specifications, find some California Customs, old Eibachs, or take a leap with the Espelir as no one seem to know what the spring rate is.

Impul made springs for the G50 at one time also.

I'll check in with my opinion on it. You won't get full travel using 300zx shocks. I chose to use Z shocks b/c they are 'short stroke'. Very similar to the Q shocks but physically shorter. This allowed me to go far lower than the Q's shocks could ever go. The biggest problem with short stroke setups is to compensate for the shortened stroke/travel, you'll need a very stiff spring rate to avoid bottoming out of the shock. Using OEM Z springs didn't cut it and I felt the front end bottom out during some cornering while hitting large bumps. That should also give you an idea of how using stock Z springs performed.

For a performance setup, I don't recommend using Z shocks. Look into a lowering spring/tokico shock setup designed for the Q. Some people on here believe that stock is the way to go. Z shocks work OK for 'low and slow' though.

As for right now, I'm playing with Z shocks and different spring rates + ground control sleeves. I'm trying to totally eliminate bottoming out in exchange for a very stiff ride! Stay tuned

Allot of us went with California Custom springs to lower the Q and it gives it quite the nice stance, at least on mine. I still have them on the Q. I think I've had them on now for about 2 years or so. I'll try to get a new pic on here so you can see.

Thanks for the reply.

Yes, I would like to see some pic's of your Q45 with the Calif springs !!

I was try to find someone that sells "CALIFORNIA" or "ESPELIR" lowering

springs for the Q... Didn't have any good luck last night,

Do you know of any source for the Lowering springs ?? in the US ??

Also, I was thinking......

What about 300ZX struts with some sort of "true" Q45 Lowering springs ?

That way you would have a somewhat "factory" lowered strut with a

Lowered Q45 spring that could handle the additional weight of the Q45 ?

And hopefully have a Lowered Q45 with a decent shock travel to handle the

Bumps in Life ??

Looking for a Q45 suspension expert input here.

thx,

Rather than begging to get knowledge for free, why not BUY some software and text books and become a student:http://www.susprog.com/index.htmhttp:// ... prod01.htm

Good evening

I want to thank the Q45 owners for giving their advice on the Suspension.

I'm relatively new to this Forum... I've only had the Q for a couple months

So, These are not new cars and I thought someone, somewhere MIGHT

did some of these mods that I want to do.

I thought forums are basically in place to inform, help Q45 owners. ??

Some people HELP... Others HINDER...

I try be a person that Helps.... Not Hinders...

So, I appreciate the advice from the Q45 owners that HELP

And I also appreciate the Q45 guru's that HINDER...

Cause, they make appreciate the Q45 Owners that truly want to Help !!

So, Back to the org questions....

Is there a place in the US for the Espelir Lowering Springs ??

I appreciate any leads.....

And I don't think that I'm Beggin' here ??

As a free service we expect posters to do their part not just be spoon fed like high school or most colleges.

Understanding the engineering fundamentals is the proper beginning of any automotive project not haphazardly taking someones advice who may not know anything about the question you asked.

At the very minimum, if you were truly interested in learning about a lowered suspension ona G50, you would have read Q45tech's previous posts on the subject.

If you want your belief to be reinforced that a Z32 suspension is better for a heavier car, try the VIP Forum. We know better here.

Capiche?

I waited 4 weeks and a little over $2000 for my JIC FLT-A2 VIP coilover setup. Its really comfortable, adjustable dampening and overall great suspension. I compare it to the Tokico blues/Eibachs but a tad bit stiffer. In my opinion i would not waste my time and money on a 300zx alternative, i loved the Tokico/Eibach setup and i suggest you take that route unless you have the money for a JIC FLT-A2 setup like mine. A Q45 is not a car to junkyard piece together a "performance suspension" it will be anything but performance and dangerous just do it the right way the first time.
