Looking good!

 

Who makes the blue springs?

I am now even more confused about the springs rates etc. - Yes you are AWD and I am FWD 855 but still...

700lb/in spring is about 12,000kg/mm

I am not saying they are right or that their cheapo springs are actually the rates they say they are either but the BC Racing Kit which I am vetting for my car comes with 4,000kg/mm rears lol 

Those 700lb/in springs you've got shouldn't move at all then, right? Thats 3X the rate that comes on the BC Kit that is becoming so popular... 

Am I missing something?

These are Blue Coil. I got them from Ben Kapelhenke, I guess they were special order as they are not listed as a part number they normally sell. So idk why it seems to need such a high amount on the back end. I REALLY should have taken better measurements or sent the Ohlins / Volvo springs to be tested for what spring rate they really were. 

I'm not sure if they are right or wrong either. I know what with a loaded up rear and bikes / the box on the top with more stuff they were bottoming out over large bumps at highway speed. So to combat this I had to put the adjustment on the shocks all the way up which then made it just extra stiff. First run out was too little movement (New springs + 8/8 on the Ohlins) New setup is being tested I guess tomorrow with a drive. Maybe the BC kit the shock part deals with more of the weight? 

I'd love to know believe me this is spring pair number four at this point. ENOUGH lol.

A comparison between FWD and AWD is tough because the suspension is completely different. This means there’s no point in comparing the two spring rates. You want to compare how that spring rate gets applied to the wheels. So without knowing the motion ratio of each suspension setup, you can’t evenly compare the wheel rate. 
 

In this particular case, the awd IRS locates the spring further away from the wheel hub than the fwd delta link suspension. That increased distance means there’s a longer lever arm acting on the spring, so the awd spring needs to be stiffer to resist the wheel movement to the same degree as the delta link spring.

First drive  - Low speed driving was pretty bouncy sort of like it was previously. The back end just needs to be lowered down a bit so that the shock is not so extended to start with. 

Highway speed was really great and seemed to do the job the way you'd want. Car still handles so so nicely, the tires are the real star sometimes I think. 

Vehicle has the rake again which is nice but that may need to go away. 

Side note, brake refresh went so well, no noises yet and the e brake works better then ever, holds the car on an incline which is nice.

makes perfect sense^

Just hoping that these ones do the trick! would like to not buy literally a 5th set of springs. At highway speed is was mint. Like I said 25mm right now going to bring it down to 16 next and see how that goes.

lesson learned. TO get further engagement from the Ohlins raise the rear springs, don't lower them. Tried 25mm from the sub frame, then 15, bounciest ride of my life. People drove around me on the road. Brought it up to where the 8" springs touch the perches, then down again 10mm and it's great. 32mm or there about from the sub frame, it's got a rake again, and it's a bit tall, however it rides great right now.

RATS! So my neighbors never seem to pickup their dog poop, and I know it's not a 100% cause for them being around. But in the garage, in what I presumed to be a relatively safe space, RATS. I saw one of these marks years ago thinking, ok something hit the car, after a wash yesterday 5 seperate marks with I would say 2 different bite sizes on the hood. 

Next 1-2 years I think the whole car might get sprayed again, if not that then the front clip and roof for sure. Looks like a cover is in order for when it's inside.

Some minor bits updates. 

Trying to stop the exhaust flex noise, made an attempt with stiffer upper engine mounts (torque rod mounts I know) still present though. 

Sends some more NVH into the cabin but perhaps worth running for a little bit. I changed the bulkhead one to a 2000 style larger mount after buying the larger Powerflex version without knowing it. 

Also went with the black race front mount purely because it's black and not purple which would have been a bit strange. Maybe Ill get over that though sad😁

I also went back to the OEM CBV for the EFR turbo. Wanted to see if that would change the impact of building boost. Not really any noticeable changes. Everything feels more powerful jumping from the p2 cars back into this. 

Next improvement will be maybe making more of the intake out of metal so i can regain some intake noise. Right now a lot of it is dampened I think by the silicone couplers. They also don't fit just as perfect as you might want so the airbox can rattle at the right engine speed. 

After that would be re covering the visible engine harness wires in some better sleeves. Currently they are covered in coroplast tape, great stuff but something else would be more attractive. Thinking of de pinning the coil leads and doing it that way versus slip over stuff. Could be fun 

Still can't remember how to properly insert the photos either. Did some nice wrinkle coat on the mounts and engine lift point as well. Came out nice! The silver spray paint was starting to show it's age.

Fine time at Carlisle this year.

Here it is not having the bumper and rear tires removed to be trailered home

Also - Further wire clean up and re wrap with the DEI sleeve kit. 

I've found that the yellow p2 circular mount works well to balance NVH and style points for the top mount.
