Bilstein 4600 + OME 880 fronts - how to drop?

[eurasiaoverland]

Hi guys

On the front of my 2.7 I'm running Bilstein 4600s with OME 880s. It's a nice setup but a touch too high for my liking.

Simple question is, what to do to drop it 0.5 to 1"?

Shall I swap the spring back to stock, or the shock back to stock? I can get stock parts pretty cheap, I don't really want to splash out again on an adjustable system.

Thanks

I might be wrong but I believe the 4600's are stock length shocks, I just installed them with '99 stock springs. I think you would swap out the OME's.
Not sure how much lift the OME880's give If you only want to drop 1" or less consider put in the 1999 "tall" springs like I did. Did you measure your wheel center to fender rim distance with the old set up and know how much you gained exactly?

If the springs are new and just installed they may settle 1/2" .

Thanks for this info.

Unfortunately I did not measure before replacing the old shocks, but then I am not sure what was on before. At least one of the shocks was non-genuine and the two did not match.

I've had the shocks / springs on for about 3 years now and they have not quite dropped as much as I would like.

I'm located in Europe and the 'stock' springs I can get here would be for a diesel, which is a heavy engine like the V6... I think part of the problem is that my 2.7 is much lighter than the other two engines so there will be some uncertainty regarding how much drop I will get... I should be able to get a cheap pair of new factory springs though.

The OME 880s are said to give 1- 1.5" of lift, do you know what this is compared with? 1996 factory springs, or the taller 1999 factory springs?

Can the front springs be shimmed up, like the rears?

Thanks

What's the measurement from the center of the hubs to the wheel well lip? From there, we can get an idea what you need.

20" is considered "stock" but, it varies as you know...

Sorry, lost track of this thread, as I am rarely in the same country as the car.

I did however recently get the chance to measure the ground to arch measurements.

Front left is 91 cm = 35.8"
Front right is 90.4 cm = 35.4"

This is on standard 265 70 16s, which are 30.6" tall, I believe. So hub centre to arch would be:

Front left 20.5"
Front right 20.1"

I'm sure the truck is higher than standard... maybe the JDM arch flares are bigger and not a good comparison with your US market 4Runners??

Thanks

I had a similar experience with my 3rz.

I went 4600s and the 99 talls. I found it to be too tall for my liking and quite stiff. Like you, I think the light weight of the basic 3rz runner is the reason.

I changed out the Springs for a set from a 2003 Tacoma access cab 4x4 with off-road package. This is a dual rate spring and lighter than the 99 tall. It sits exactly 1 inch lower in front now using the same 4600s. It rides so much better. If doing it again, I might look for Springs from the same Tacoma but the 4 door version. They are slightly heavier than the ones I have and I think would be ideal.

I'm away for a week or so but could provide measurements later if wanted. My rear on ome2906s sits 1/2 inch higher than the front when empty. With 500 lbs in the truck, the rear is 1/2 inch lower than the front.

Just wanted to let you know you are not the first. The 3rz is a different beast.
