I would not remove that if I were you.

Everything is removable if you can cut it off, otherwise no

Haa haa guys, I was just thinkin of the possibility to move the lower bracket around another shock, but no luck then.

I didnt say I was having trouble, I was saying (I think) it would be better to use 10" springs for stock wheels

for the wheel gap I have with 12" springs, I would have to tighten the adjuster alot, putting ALOT of preload on the springs to close the gap.

it needs a good 2" drop to match the front with 1 coil cut, so 10" spring would do that perfectly

BTW here's a quite nice calculator for spring rate http://www.ridetech.com/inf...ing-rate-calculator/ if someone feels the urge to use "correct" springs in their setup

After reading through this thread I was nearly sold on the 7in adjusters, QA1 12 inch springs @ 300lbs. I was going to fully remove the stock perch and have the sleeve sit all the way down. Now I'm worried... I wanted to do the coil over conversion to allow for wider rims in the rear. I have a free pair of 265/35 r18 tires off my spouses mustang I wanted to use on the rear. I'm still shopping for rims to make it all work. That tire size means rims at 18x8.5 minimum, but preferred 18x9 inch. Now I'm worried I might experience this issue, as rims don't offer as much offset selection with our lug pattern. I don't need my lower spring seat/adjuster hitting my tires. The plan is to lower the car so the fender sits about an inch above the tire. Would it be better to use a 10 inch spring to get the lower ride height I want, but avoid the seat/tire contact? Or would it be better to have the sleeve rest on the stock perch welds to hold it up higher. Then what spring length would i need to get only 1 inch fender gap?

Thanks to you all. Great info in this thread. I figure its better to ask before I collect parts and have to re-buy a shorter spring.



I plan to do this install as soon as I can get this question answered...
I have since learned the 10 inch spring with the 7 inch sleeve should get me above the wheel and tire, but If I really want to push the tire width and offset... and maximize my space, would it be better to go with a perch mounted sleeve with the perch trimmed super tight? This would give me a few more MM of clearance with the sleeve not b/w the strut and tire? Yes/NO??? Or will 18s sit tall enough that their height will put them at or above the stock perch location and make it irrelivant?

It seems where the adjuster is at is about where the spring perch is normally at in most of the finished pics. Couldn't you keep the perch, get a shorter adjuster sleeve, and get a 8" or 10" spring? I know it would be easier to get coil bind that way but as long as you aren't driving crazy it should be fine I think.

I know I could be way wrong but that is why I am asking and not just doing. I just want an easy, safe way to lower the car about an inch to get rid of the big gap in the wheel wells.



Same question I have! I ahve seen some of the completed kits offered have the sleeve at the stock perch location, but I have heard people say the 8 inch spring has popped out. So that means 10 is safer. Well will that still give one the adjustablity to get decently low. Again I'm hoping to go as low as I can.

Thank you! I have been searching and searching and have not yet found a thread weighting these pros and cons clearly enough for me to be 100% sure of which route to go... THX!

This doesn't make sense. To close the wheel/body gap you don't tighten the adjuster, you lower it. If you tighten the adjuster you are raising the car more, no matter how long your springs are.

Just FYI, Speedway has a garage sale on a 5in 2.05in diameter sleeve and nut for $22

I bought a pair of sleeves, a spanner wrench and 12" 275 springs for $150 shipped

Also, use discount code 1409w as that knocked $10 off my order

ok here is my diy coil-over thread in process showing my build with the 10in 300lb summit springs and 7inch Coleman racing sleeves

could not have done it without this thread. +1 fierohoho

just to report back in on the completion of my build. I was able to fit 265/35 18s on 18x8.5 with a 45 offset on the rear. Seems like I have about a finger b/w the tire and spring perch. Car is sitting now with 3 fingers height b/w the tire and fender lip (perch sits 31 threads up from the bottom) The tire sticks out of the fender lip ever so slightly, but WAY less then a 38 offset on a 9 inch wheel. Pics will be posted in my thread later, which I linked in the post above this
