I put a strange s60 in my car a few months ago and the bigger axle tubes brought the rear up more than stock. I still have the stock springs with the isolators in and was curious if doing the heater hose mod will bring it back down to factory height. Also, would doing this change the pinion angle at all?

No, the heater hose mod would not affect the suspension in any way - just make the body sit a little bit farther down on the suspension. Slightly lower center of gravity of course.

The only thing I would think to correct is axle centering. Static height change will place the panhard bar in a different position than factory and push the axle to the driver if lowered and vice versa. If you bring it back to factory height there should be adverse effects on your suspension.

I have the S60 in my car and I did the heater hose mod. I am still using a stock panhard bar. My rearend moved to the drivers side about 1/8th of an inch. An adjustable pan hard bar will fix this or I believe UMI has a panhard bar relocation bracket.

I am using a UMI torque arm and had to use the inner most bolt holes on the torque arm (where it bolts to the rearend). I also had to cut off the top of the bracket where the outer holes were, otherwise the torque arm would hit the floor.

You should double check the pinion angle.

Like LilSlo1 said, adjustable panhard bar will correct that. The relocation kit we offer for the panhard bar will allow clearance for a larger diameter exhaust kit. And it's always a good idea to check pinion angle!!

Right now my pinion angle is at -2 (which I'm pretty sure is the stock setting) with a umi non-adj torque arm and relocation crossmember. How much would that change if any if I did the heater hose mod?

Just want to bump this up. Would an adjustable phb be 100% necessary if I did the heater hose mod or would the non adj. one I have now be fine?

Thinking on giving this a go also.

I don't think it is 100% necessary unless you have a wheel rub problem.
I've gone 10.70s @ 126 with a stock phb and the heater hose mod on my car.

I have a 275 tire on zr1 wheels so I wont have any problems with anything rubbing.

I wouldn't say that it is 100% necessary at all but it will shift the rear end over to the drivers side slightly. It won't be as extreme as if you were using lowering springs because you won't be lowering the rear end as much but it will still happen.

I run my S60 with the heater hose mod with no problems, both with stock sus and aftermarket parts. You don't need any adjustable components to center up a S60......it's not a Moser.

That's what I was thinking since the s60 went in exactly like my 10 bolt.

Thanks for the input Kyle, I appreciate it.

It really doesn't have to do with what kind of rear end is in the car but with the car having a panhard rod to locate the rear end side to side. No matter what rear end you put in the car it will react the same. If you lower the car the rear end will move towards the drivers side, it may not be much due to the small change in ride height but it will definitely move.

Not a problem, if there is anything else I can help you out with just let me know.

^^^ Kyle, You are correct about the panhard bars effect on rear centering with ride height changes. With the S60 having larger axle tubes and correspondingly higher spring perches, the hose mod lowers the car back close to stock ride height. Strange's precise alignment of the suspension mount brackets during welding minimizes the need for adjustable suspension components. The same cannot be said for all rear end manufacturers.
