Other than the small difference in drop, about 1/2", are there any advantage or disadvantages to either? Experiences and thoughts please............

Joe, I don't think anyone will have any experience with the Progress springs yet. We just picked up the first shipment yesterday. :thumb:

The progressive ones just hit the market and Eibach still uses the same springs for both the Cobalt and HHR to my knowledge.

I have 17 by 8 wheels on my 2LT, do you guy's think I would have any problems with GOLDLINES?

You might have trouble getting a set of Goldlines from what I understand. :confused:

The stock HHR wheels are only 6.5-inches wide. Depending on your new wheel's offset, you will most likely need to roll the fenders with 8's.

I'm running 17x7's with a +42mm offset and had to roll the rear fenders with Gold-Lines.

Again - it all depends on the wheel offset. Look for an 8 with a +45mm offset.
You shouldn't have any issues with the Progress springs - they have slightly less drop:

Mike,
I have American racing Rogue wheels with a 35mm offset.

Do you mean that I won't have to roll the fenders with progress?

Hard to say. You might have to roll as 35mm is a lot LESS offset than stock.

With a wider wheel, you need MORE positive offset to keep the wheels "in."

Cant' really say until you bolt them on...

:confused: :eek: :roll:

Mike... Google is your friend! ;) Look up wheel offset and come back when you understand the relationship between offset, wheel width and where the tire ends up.

FACT: At any given offset the tire tread will be in the exact same location regardless of the wheel width!

On the HHR the first problem to manifest itself is where the outer rear tire will hit the fender lip near the edge of the tread. Wheel width will not change that, only offset.

Joe - we've been through this before; both online and on the phone....:roll:

Your statement only pertains to the absolute center of the tread. A wider tire/wheel combination is still wider - and will rub (especially on a lowered HHR). Increasing the positive offset will tuck the wheels "in" under the car, increasing clearance.

Why not see what the wheel manufacturers are building for the HHR. Most new HHR bolt pattern wheels are being built with 42mm offset on 7" wheels and 45mm offset on 8's. They must be wrong too...:lol:

Bottom Line: If you want an 8" wheel on the HHR - you will need to increase the positive offset to make it fits without rubbing against the outer body. (*Just ask any of the guys who have already lowered and done it.)

Other than the small difference in drop, about 1/2", are there any advantage or disadvantages to either? Experiences and thoughts please............

Joe
Has anyone dropped just the rear to level theirs out?

I have 7.5's with 45 offset...no rub.

Right - because the stock offset is 42mm - and since you have more offset than stock, your wheels are tucked in slightly more. Make sense now?

Positive offset is the reverse of normal wheel "offset."
Most FWD vehicles have positive offset wheels.

So Mike, If I go back to my stock 17" wheels the Gold Line's should work Right?


Also, if I am reading the threads correctly, I should get the camber adjust and shims too?

Joe

Hi Joe, I ran the Gold-Lines with my stock wheels for 6-months with no issues, and several others (with both 16 & 17's), have done so also. You just need to make sure that if you are buying new aftermarket wheels, they have the proper offset to stay tucked.

Hope it helps,

Thanks Mike, I just put an order through to you for the GL springs, shims, camber and sway bar! I am going to try my after market wheels, if they rub I will go back to stock until I can find some AM wheels with spec's that will work.

Joe

Got my goldlines today from autotrucktoys.com. Will be slaming it Monday!!

Any comments on that Mike?:confused:

Sure: old stock. No one has the new ones yet.

Joe, I don't know if you found the answer to your question and don't know if I can shed any light on it or not. I had the gold lines on my HHR and they worked out great, but I didn't know that Progress made springs for the hHR. However, knowing Progress springs I can say that they do make a quality product. I had a set of Progress springs on my Focus and they performed great. As a matter fact I've sold the car and the progress springs are still on there doing their job. -Dan
