Coilover angle

Post by Z()LTAN »

Hey fellas, ive run into a bit of a snag with packaging the bumps/coilovers on the ute.

On full droop the coilover hits the bump can, i dont want to move the bump as its already too far from the shock for my liking.

Im running the coilovers on a bit of an angle in and back.

Now if my spring rates and valving are a bit overkill since i put the ute on a diet would it be ok for me to run the coilovers on a bit more of an angle front to back? I believe this will give me the clearance i need.

Looking for replys from people who have tested coilovers layed over and not someone who knows some guys dogs owners brother that has some fully sick patrol. ;)

Cheers fellas

From what ive been told and learning, The more you lay them over, the softer they get.

External res only. Emulsion must be straight.

From my understanding with what you want to do with your truck, I would try and achieve a vertical angle at full compression. The more you angle the shock the heavier the valving and spring rate would need to be, to accomplish your body height, suspension frequency, and travel of the suspension.

How much of an angle to you think you will need to lay your coilovers over to gain enough clearance?

Right now with clearance everywhere in the cycle i have 15* in and 5* back.

With the diet the ute has been on then calculated spring rate is a touch heavy. With the fuel cell and the rest of the tray it should get close. So i have a bit of valving/spring rate i can sacrifice for shock angle. Just wondering if there was a rule of thumb like for ever 5* you lose 5% efficiency. Obviously its not going to be a linear decline but.

Not sure if you have read this http://www.pirate4x4.com/tech/billavist ... rs/Part_1/" onclick="window.open(this.href);return false; but it is a very good read.
From the photos in your build up, is it possible to outboard your coilover more, or make a pad in front of your diff to allow you bump stop to hit.

The bottom is about as wide as id go so i can have a good choice of backspacing if the diffs end up too wide.

I have brought the tops out 2" per side since those photos which has given me clearance at the bump for full droop.

I did think of hanging the bumps off the back of the axle inline with the coilover, looking back now it might have been a better idea...

Cheers for the help simkell

The spring rate and shock absorption is effectively; 98% at 10*, 92% at 20*, 86% at 30* and 74% at 40*.

I haven't personally done it with coilovers, only shocks - the numbers are the same though.
