SPL rear titanium mid links, springs???

synolimit

I'm worried about something if someone can help...

I installed the spl mid links and the 6" swift 10kg springs. The car is at a ride height of 26 3/16th on both sides. I don't remember where the car sat before the install with the swift spec-r's. I know it was 26 something, I think high 26. The spl mid link is about half way to get to that height and where spl said it should be.

The issue is if I jack the car up the spring almost falls out of the bucket. If this happened it'd be a total crash or worse! So basically I have zero preload if that's what you call it. I've seen Z's on three wheels before so there is a chance the spring could pop out on a track. Not to mention the loud banging all the time as the spring pops in and out over big holes all the time beating up the upper and lower buckets.

What do I do? Buy an adjustable length shock?

Almost popping out, only one side jacked up.

What did SPL say when you contacted them with your concerns?

They advised to run a 7" vs a 6" but then stopped when i stated that wouldnt make sence with the ride height i wanted. If 6" is dead center on the adjuster then 7" would just force me to lower the adjuster putting it not dead center but have it 1" lower unless i wanted to look like a 4x4. They agreed and i just left it. After some time the spring stayed solid even when jacking the car up. I never had issues and the car tracked perfect even tight fast autox events. Only time i thought there was a problem was when i fully unloaded the spring when jacking the car up with in first few times i did it. Idk why it got tighter over time but they did and i never had noise DE is stating.

I have 7" springs, but no 4x4 height. The perches are all the way up, and it's at OEM height, or close to it

I haven't checked the bushing, but nothing was out of the norm. I can hear the spring decompressing when I'm going over a bump...
I'm also at the extreme of adjustment on the arm too

I think that's a prob then. A 7" spring at oem heights probably putting it at an odd angle. You saw my pics and gomers, 6" spring with adjuster at half way and straight when compressed. You need to slam it or go 6".

You need a helper spring Swift Helper Springs to keep a load on the spring. KW provided me this information as I ran into your same issue Swift Helper Springs H65-070-008. Also you need to find a better alignment shop or if you did this yourself, you need to correctly adjust the top (there is a bolt you can adjust) to move the top spring so when the car is on the ground, the spring still stays straight up and down...vs the way yours is now at a weird angle.
