Sorry I'm just getting to this, work and shit.... So yeah, as I said in the thread that is linked, I was looking for an SR5-like ride but just a little taller. That's basically what I got. The low speed compression (the soft wallowy feel) is a little firmer but it's not bad at all. Perfect really. The high speed (big hits) is also firmer and that's good too. My town has a lot of speed bumps and roundabouts and while I went over them from the beginning, it is much, much less jarring. I noticed when installing that I have more down travel as well. But the main difference is in the turning, it is so much better it almost feels nimble. The lack of caster angle makes the steering more twitchy (I kept the stock UCAs) and the firmer low speed means I can fly down I-70 no problem. That might change when I get 33s though. Offroading performance is good too, I did Bill Moore Lake two days after and I definitely noticed I was clearing things I normally wouldn't. Jumping the water bars felt nice too :doh:. Install was straight forward, definitely disconnect the sway bar but you don't need to touch the LCA cam bolts. Use a monkey wrench to keep the rear shocks from spinning. When tightening the top nut for the rear shock make sure the bushing isn't bulging.The three studs on the top of the strut cannot handle the factory torque spec without stripping. I called Mike and he relieved me by saying that those bolts don't do much at all and that hand tight with a box end is all you need. To fix my problem I just tightened another nut on the stripped one and called it good.The measurements are from center hub to wheel well opening:
these words are white Driver so are these these as wellllllllllllllll Passenger
these words are white 21 7/16 so are these Front these as well 21 14/16
these words are white 24 3/16 so are these Rear these as welll 24 9/16
these words are white +2 12/16 rake so are these Front these +2 11/16 rake
Unfortunately I didn't measure stock, I was itching to start. I know I wanted to keep some rake, but I think this is more than it used to be. Someone could measure stock if they wanted to. The parking lot was not level side to side, I was not in the car, and I had 3/16 tank of gas. I can't comment about any MPG differences or washbaords. Overall I would highly recommend, the car doesn't feel tired anymore but It's still comfortable enough to do 30 hour road trips (Naples to Golden is long). If you have specific questions feel free to ask, I turned email notifications on so it won't take me two weeks.

No there aren't, sorry. With KDSS though, you can use even height front coils and offset rear coils (or a rear spacer) and still achieve a level stance. That's what I did in my 2014 with KDSS

Hi. No, we don't have any coils to fit other brands of coilovers. The closest/only thing we are offering is new coils for the Bilstein 6112 to match the TRD Pro stock coils, but 1" more lift than those. They're not a heavy spring rate like you're asking for.

Ah bummer but thanks for getting back to me! I def got too much weight for a stock spring rate, the quest goes on

I haven't had more than my bike on it yet. With stock you could tell when it was fully loaded.

After a busy boat selling season, I was finally able to get out in the woods and get some pictures. I have had this suspension installed for about 4 months now with roughly 5000 miles on it, and I have to say I am loving it. I travel 45 miles a day, six days a week, on an interstate where the average speed is 80 MPH. This suspension set-up rides like stock but takes out some of the nose dive, and handles corners much better. I can now weave in and out of the traffic with out the body rolling as much. My only regret is not going with the 3 inch coil for the front. Not sure exactly how much lift I got from the 302 because I forgot to measure before the install. If any of you have stock measurements from an SR5 maybe you can tell me. From the center of the hub to the bottom of the fender I get about 22.5 inches on the front on both driver and passenger side. The rear is kind of strange with 24.5 on the drivers side and 24.25 on the Passenger side. Would have though that would be reversed with no trim packer.

It's looking good. Within 1/4" (from memory) is within factory spec for left to right variance. My driver's side is also taller than the passenger side. I haven't done the "trick the KDSS system" trick yet to get the piston to retract a little on the driver's side.
How do you have the 5100s set in the front?

Thank you for the great customer service, Mike! Here's my 4runner with King shocks and Dobinsons C59-325 rear springs

New rear variable rate coils
Hey guys, we just had our first delivery of stock of the C59-701V rear long travel coils.
C59-701V - Variable rate, 600+ LB heavy rear load weight, 3" lift, long travel. 500/500mm, 210-245LB variable. Designed for those with heavy full rear bumper, tire carrier, roof rack, RTT, drawers, and fridge. Rides very well with all that weight, as well as when loaded even further.
These were specifically designed for 2 customers with a lot of weight in the back of their 5th gens, specifically 900-1000LBS of extra weight over stock when fully loaded. Daily rear accessory weight is around the 600LB mark, between having a full size rear bumper with tire carrier and spare tire, jerry cans, Hi-Lift Jack, Roof Rack, RTT, sliders, Drawers, fridge. Then they add extra gear for their trips.
They're not easy to install due to their open length, but once installed, they're still riding at 3" to 3.5" with all of that weight, and extremely happy with the ride quality over other options they have run in the past.
Friendly warning - Don't attempt to run these or any of our heavy load coils unless you're running the accessory weight listed next to them. You'll either over-lift the vehicle, or the ride quality just won't be there.
