For sale brand new rear coil springs for G1's.

I sent out a sample Daewoo Matiz rear spring and had them copied, 50 pair. They are brand new, powder coated black, made in California.

I have installed them in my latest acquisition (red G1) and they preform as expected, increased ride height of about an inch, virtually no bottoming out.

$90.00 picked up in Southern California.
$100.00 shipped anywhere in the continental US.

Great Scott, You finally found a way to put a little SPRING in your life.
Seriously good job.

Great Upgrade

Have had my G1 for almost 4 months now and loving it. My girl has been driving it every day on her 120 mile round trip commute every day. The only thing that has been an issue it the ride. I spoke to Scott a few times and he said he could fix it, and was working on getting a bunch of new springs made and would let me know when they came in.
He hit me up the other day and told me that he got his shipment and had my set ready. Headed over to see him today and got them installed. What a difference! The ride home was soo much better. Didn't bottom out once on the freeway and made the drive much more comfortable. Dropped it off at my girls place and got this text a few minutes ago.

"Omg!! The car is so much better!!! Thank you! And thank you Scott!!!!!

Sits about an inch higher (notice you can see the H logo on the wheel now)

If you are looking for a better ride out of your G1, hit him up and get a set. To date the best improvement that has been made to our car.

Thanks Scott!!

after installing the new rear springs, is ride noticeably smoother? would you be able to go over speed bumps or dips a bit faster without bottoming out?

It is noticeably smoother without a doubt.While driving the vehicle today I didn't bottom out once. The biggest difference I found right away was when going over railroad tracks. Every time I would go over them I could feel the vehcile bottom out. I didn't go over any speed bumps, but didn't slow when going over dips when driving. Even when driving the freeways it would do the same over dips and bumps in the road. It does not do it anymore.

wow! just saw this, Great Job Scott, Thank you! these are on my list!

 

[Willie Williford]

Using the new springs, it will also "tighten up" the steering, which I liked better.

Too bad you guys didn't call me, I would have liked to been there. I NEED A TRIP.

Ok, just a follow up on the springs. My girl took a short last night and liked it as I stated above, but after taking it to work on the crappy LA freeways this morning on her 65 mile drive, I got this text.

We are both believers! Looks like I gotta keep his number secret and keep her off of the boards here though. :shhh:

PM sent

thanx

 

[wrast]

I think I'd like to get a set of these too. PM on its way. Any noticeable change in mpg from the extra height?

 

[Willie Williford]

Any change in mpg would have to come from a "wind tunnel" test.
As said before it will change the steering somewhat, but the "normal" driver would probably not notice.

Any change in mpg would have to come from a "wind tunnel" test.

I believe this was at least informally tested previously. I'll see if I can locate the thread. The consensus was that raising the ride height does cost a small amount of MPG. This is consistent with prior art and general automotive knowledge. I know that cars with adjustable ride height (air suspension) such as Audi and Mercedes claim about a 3% MPG improvement by lowering the suspension at speed.

 

[Willie Williford]

The key there is "at speed".
Maybe at a high rate, but I doubt it would have any effect around "average driving speed", 60-65.
I have the springs on my LRR2 and do drive above average speed most of the time.
Too may other variables to come to a definite conclusion.
I believe with the other cars, they adjust the front also. With the spring addition you are only adjusting the rear.

My opinion.
Willie

 

[KLR3CYL]

I haven't noticed any difference in fuel economy as the difference in ride hieght is about an inch and the spring rate is increased over stock. The purpose for the springs is to increase the ride quality.

Scott
An interesting evaluation would be an alignment check before and after the mod.
Just to see what the change does.

I still highly recommend the springs, and I carry a lot of extra weigh in the rear cargo area.

Here is the thread I was referring to:

http://www.insightcentral.net/forum...ical-issues/16601-aveo-spring-mod-w-pics.html

and the relevant post by Mike Dabrowski:

Just to add another point of view, I did some experimenting with rear suspension height and the effect on areodynamics. As you may remember, I had added adjustable air springs to carry the extra 300 lbs of batteries and the e-wheel I could dial in any rear suspension height I wanted on the fly, and found that getting the rear that high had negative effects on MPG at highway speeds, as it changed the angle of air flow of the front of the car.

I'm not saying raising the read 1" is going to make a noticeable difference to most of us, just that there is likely to be *some* negative effect on MPG. I think I can say that for most people the improvement in ride quality is a worthwhile tradeoff, and I'm seriously considering these springs for myself.

I have heard that cutting a coil or a half coil out of the upgrade springs will lower the ride height back to stock but will maintain better ride than the oem insight springs. Any thoughts on this?

 

[KLR3CYL]

I haven't cut any of the coil off at this time to try to make the ride height the same as stock. However, you can cut off any amount from the bottom of the spring to adjust the ride height. If I was to cut I would start in small increments, maybe a 1/4 of a coil and test fit the spring. The top of the spring is round and flat, the bottom fits into the pocket on the axle and needs to be oriented on the bottom so it fits correctly.

HTH,
Scott

You need to be careful. Upgraded springs have higher spring rates. So, to end up with the same ride height under normal load you start with a shorter spring. Shorter springs may become unseated at maximum extension of the suspension. So there is a balance that needs to be struck.

 

[TRI]

Cutting a spring also increases the spring rate.

Aerodynamic effect: the optimal degree of a rear diffusor is 4 degrees. At different angles the drag increases so less mpg.
For most cars drag increases significantly above 100 mph, in the I1 you feel it even sooner as usual. At 60-65 mph you may feel it already but if the ride Quality around town on bumpy roads is much better I'd go for them too.
