Job is done, wheels are on, and I’ve done my test drive. So far I can say I’m absolutely satisfied. I ended up searching online inventories yesterday and found a Lowe’s 25 miles away with a corded 1/2” 450lbs electric torque wrench in stock (and it came with impact sockets in the sizes I needed...
To make this whole process more fun and potentially fraught with more rusted bolts, Assuming the lowering springs work out for me, my OEM springs may be going into my sister’s ‘08 model since the 2nd gen got better springs than the 1st gen. I think 1st gen may have been using Mz3 springs.
Okay, just went out to grab something and whipped out the tape measure. OEM 5 rear springs appear to be 3.25” ID. H&R 3.5” ID. Not sure if being partially compressed would make them open up an extra 0.25”, so I’d assume they’re a slightly larger ID.
No home gym here, but there’s a pretty well stocked gym at my work (once I get off Covid leave and can go back to work). Springs are already in the car, but I was kind of interested in putting defined weight in the back of the car and seeing how the suspension holds up.
The springs are the same overall length, but you can see in the photo that the spacing is larger on the H&R spring on the lower section, so should have improved weight capability.
I remember one memorable brake job on my sister’s 5. Front axle done in 20 minutes. Rear axle one rotor took 45...
Noted. I’ll measure them the next time I’m out there. Had a delay on a seized bolt so it’s still up on stands. Both springs are in, though I should be able to get a measuring tape through the lower coils to check them out. Off the old Mark 1 eyeball they look nearly identical in ID diameter...
Also I’m halfway through my suspension job. Passenger side is done, but the lower bolt for the driver side shock is not quite seized. I got the driver side spring out, and had the head of the shock bolt about 1/2” out before dinner last night, so I sprayed a bunch of PB blaster on it and...
Or make friends with a person who has a spring tool which measures the spring rate. Got a funny story from a guy on another forum with a new Mz3. Took his new red aftermarket springs and set them off in the corner while he was doing other stuff, then realized he’d put the red springs in with...
Hard even with those numbers.... so much flex just based on driving habits. I can easily get mid-upper 20’s driving mine (with nothing loaded up of course), and low 30’s on the highway..... sometimes. My au pair’s tend to have heavier feet and average upper teens to low 20’s at best.
Also my shocks arrived yesterday. Current plan is to do some measurements today, and drive the car to get familiar with how it’s currently handling (it’s not my daily driver, so basically any time I drive it it’s feeling different). Hopefully install on Tuesday, weather and children permitting.
At the risk of continuing off topic do you have any other pictures of how you installed everything up there? How much weight have you put on the roof with this set up? I was chatting with someone on another forum who was asking about putting a roof tent on top of his 5, and wondering about...
AnthonyVerde in this thread posted that he installed OEM CX-7 springs in the rear of his 5 years ago. He noted a 2” lift as a side effect of the rear end holding weight more easily without bottoming out.
I don’t know ifI’ll have any issues with the lowering springs, or is they may end up riding...
Replaced the 8 year old Wolo compact dual air horn in my sister’s ‘08. It has been having issues for a little while and was intermittently not working. It was a loud horn but still pretty high pitched.
Swapped in hella super tones. I’d have loved a nice front facing grille mount, but the 5...
