Height adjusting IE stage3's

[DarkWing6]

I run HR race and went w/ thicker rear pads......I run 15/7 w/ 225/50's and have no rub issues, ......try thicker rear pads, or roll rear fenders or bang in rear inner fender area.

Where did you get the thicker rear pads? I wouldn't mind bringing the back end of my car up a bit.

Ok, I think this is a common misconception about what I send. This makes entire sense what you said Mystical, but when people talk about stiffness in relation to springs, are they incorrect to speak about springs in terms of damping? I mean, do the springs not dictate any transfer of shock from the road for feedback to the driver?

Springs= strictly reduction in body roll? or no?

Thanks for clearing this up

It's far too complicated to explain in this context, but yes, springs really do not change much in relation to ride quality. I remember when Axxe here had Stage III's and stock dampers, it barely felt anything different from stock (ride quality...body roll was way down).

If you're looking to change the ride quality of a car, don't even look at the springs (unless you have linear springs like those in coilovers...now those make a large difference in relation to spring kits).

very good info here guys, thanks

so is it 100% true that IE stage3 is exact same spring as H&R race?

Thanks
Alex

Too close for any mortal to tell the difference.

I just put on my koni's and IE springs. The rear is a bit lower that I expected, and I also think I may be bottoming out. Anyone else with Koni's and IE springs experience this? There is a thump when I go over bumps.

Other than that, the ride is really not too bad.

With 570lb/in rear rates and the enormous travel the rear dampers have on our cars...there's no way you're bottoming out.

Check for something else.

Dealer carries 9mm pads.

[MrK]

If we're talking rear pads, I believe the dealer carries 10 mm pads (not 9). I should know, I installed them to keep the touring from sagging in the rear.

[DarkWing6]

How thick are stock rear pads?

[Mystikal]

Oh...no! Someone's car is gonna be 1mm higher than I told them! HOW DO I GO ON WITH MY LIFE AFTER THIS?!?!?!?!?!

Okay seriously, you're right.

And stock pads vary depending on year, options, etc.

[MrK]

Oh...no! Someone's car is gonna be 1mm higher than I told them! HOW DO I GO ON WITH MY LIFE AFTER THIS?!?!?!?!?!

Okay seriously, you're right.

Actually if you wanna be EXTREMELY accurate about it: (LOL watch this)

10mm rear pads DON'T raise the back of the car 10mm, they raise it 13.1mm, due to the fact that e30s have a trailing-arm rear setup, and arm acts as sort of a lever, and the spring is closer to the 'focus' of the lever than the wheel is. THEREFORE, the car is raised a teeny bit higher than 10mm with a 10mm pad :D

Who gives a fuck? Let's see a show of hands LOL

[Mystikal]

I thought the E30 rear ratio was 0.67? Meaning 10mm at the springs = 14.9mm at the wheels.

LOL, don't get technical on me!

[2002maniac]

You guys are all wrong.

[MrK]

I thought the E30 rear ratio was 0.67? Meaning 10mm at the springs = 14.9mm at the wheels.

LOL, don't get technical on me!

I dunno man, I measured my ride height before and after 10mm pads and I got closer to 13mm

And before you ask, yes in both cases (before and after the pads) the car was moved back and forth to let the suspension settle.

Go figure:?:

Edit: Wait! I got it! My trailing arm bushings are a little worn, so there must be a little play in them, causing the 'focus' of the lever to wiggle. That's probably why my car sits 1mm lower than it should LOL

This is getting sooooo anal :D

[DarkWing6]

Are you guys taking into account that this is rubber and will have some give. The pad itself may be 10mm, but after it has the weight on it that is going to change.

[MrK]

Awwwww shit! Another variable! LOL I give up :D

[DarkWing6]

It might be faster to order all 3 sizes of extra pads, wait to have them shipped, install them, and measure. :D

Good attempt at sounding smart though. ;)

I'm just gonna assume that if I want my ride height higher I'll go buy some 10mm pads and give it a shot.
