Yeah honestly, it's decent advice but actually not the way I roll typically. Everyone has their own way of doing things, their own system, and advice that's a little to syrupy tends to make me chafe.

I've been holding back a little here, but I think it's time to kind of state my MO. Every serial killer has one

I have been driving fast cars for 25 years, with only one track session in the form of the Porsche Advanced Driving School. I just set up the suspensions on two of my cars, each one with a different purpose than the other.

Keep the following in mind about me:

- I never start simple. I start with what I perceive to be the best and I go from there.

- I am a lot like Devore in the sense that he enjoyed the mechanical design and tweaking probably as much as he enjoyed the driving, if not more.

- I basically already know what I want and what direction I want the build to go. Sometimes I have the semblance of asking for advice but I am not sure I actually mean it.

- I can and will build everything and anything on this car and do stuff no one else has seen if I think it will improve the car. I want to kind of dispel the idea that I might be a noob on this build....This is my FOURTH 928 and I have a frigging 4000 pound CNC Mill in my garage for chrissakes. I built four Porsche motors in the past 12 months. My mechanical skills probably exceed your average shadetree dude.

So yeah, thanks for all the helpful PMs and phone calls, much appreciated, but we're good guys, we're good

Default Options for Motons

When I was looking for my own racer car, the $1000 per corner for the Motons put me off. I thought "there has to be something between say, the Koni option at $900 for all 4 and the Moton option at $4000 for 4, right?"

That's when we developed the PRO shock kit:
https://www.928motorsports.com/parts...ension_kit.php

Been very pleased with them, aluminum shell, twin-tube design, true double-adjustable, and our price includes springs and spring perches and mounts all for $4300 (all 4 corners).

I will agree with Greg that a good 600/400 spring and shock package can take you a long long ways, even if its just Koni's... allowing you to sort out the car and learn how she behaves before making a big suspension investment. You have a lot of modified/custom suspension links on that car and you might want to make sure they are functioning as intended before throwing yet more variables into the mix.

Just a thought.

Carl,

Wound up picking up a set of double adjustable custom Konis from Darien Nunn. For whatever reason, if I am reading the part numbers right, my car currently has 1000s on all four corners!!!

The Konis that are currently on the car (besides being rusted and ugly) are all out of ride height adjustment in the front, where they are still way too tall for my liking. The ride height out front is almost stock it's so high, so they just jacked up the rear to suit. Looks like a 4x4.

So I will fiddle with the new Konis and see how it behaves and go from there. They were practically free anyways.

Good grab! But that spring rate on all 4 corners is likely going to over-steer, and may have a hard time putting the power down especially on corner exits. I would worry that the 1000lb rear springs would be too stiff to allow the rear suspension to do its work. It will depend on what your finished weight and weight-biases comes in at.

Generally, the 928 seems to like a spring rate package where the rears are about 65% that of the front.

That's a front/rear spring rate like the 600/400; or 800/550, etc.

But I know you have other racers and experience, so this is just an FYI about something you probably already know about.

So instead of between you went for the outside upper.

This is with no engine in the car, correct?

Randy -

Maybe you didn't understand what I wrote.

The price for the Motons is for the shocks only. You still gotta buy race springs and spring perches and hardware.

The price for our PRO kit includes the springs, spring perches, and hardware. The PRO shocks are less expensive so
we are able to do this for the same price as just the shocks only if buying Motons.

Kinda sorta....so when I bought the car, it had a long block in it but more of a mock up than anything. It was an 82 or 83 16v block with heads and cams, all clearly designed for mock up purposes. So I'd say 50-60% of the weight of a full engine was there and it was still riding way high. I'm not convinced that the hundred pounds of gear and fluids it was missing would bring it down that much.

Also, the front shocks had their spring perches bottomed out to the lowest possible setting and that tells me he was trying to lower it as much as possible but wasn't getting there.

You have to remember in the early 90s you couldn't just go out and buy this stuff for a 928. Today, your 928 is too high....easy...you can pick a dozen coilovers that will give you anything from stock ride height to slammed.

Your suspension was probably not settled, that's why it was so high.

Uh, no. It was settled fine. It has been rolled around all over hell's half acre and it probably has more miles being pushed than most cars have being driven. Also, take a look at all the pics out there of when the PO had it. Always high, almost stock ride height.

Look at the picture below. It looks like a monster truck. The only car I have that rides that high is my Range Rover

I also blame the 1000 pound springs as well. Too much spring on this car.

S'okay, I shall fix it!

Damn! Thats a sharp looking car. Its potential is oozing out in that picture. Never noticed the lollipop lift point added to the car. Clever. Is that braced up to the roll cage inside the door? I would think so...

We are delighted and honored to be building the motor for this beautiful car.

Thanks Carl!!!

The lifting points (one per side) were a Devore creation and you can see them on the earliest pictures of the car. They are actually not tied to the cage, but cleverly, are a section of heavy wall pipe that pierces the longitudinals and are welded in place on both sides, with a thick backer on the outside.

One of the first things I did was try jacking the car up from those.....they work friggin great! Today we just would have used on board air jacks, but these are neat for sure!
