I read that the G8 will sit at least .5" higher than the prototype we've seen. Anyone know if OZ has lowering springs out already for these and how they react to lowering with the new suspension design?

I am sure Pedders will be providing packages to lower the G8.

I think the show car has HSV springs in it, so I'm sure that those will be available through JHP or the like.

See if this works

I'd say it's a must if your roads allow it. I'm glad I live in the desert. :D

Wow - great comparative pictures trishield. good work!


Man, that little bit of lowering does the car so much good...

It's NEVER To Early...Frank:p

TriShield,

How much is this lowered? 1"? What did you use to lower it? Pedders? Which parts? I am planning (saving $) for mods to the G8 when I get one after they are released in the US.

This is what I am after (top picture), lower picture is original before I Photoshopped it.

These springs just divide by 25.4 to get the standard equivelant.
PEDDERS (http://www.peddersusa.com/Pontiac%20G8%20Zeta.htm)

I took this from my post on another Forum to give you an idea -
When I got the car lowered by Pedders Sports Ryder Coil Springs 2944 and 2955. The results were as below -

From bottom of rim to guard (Pedders method of measurement) -
Front - both 645mm
Rear - both 645mm

From centre of rim to guard -
Front - both 365mm
Rear - both 365mm

From these figures the front has come down 35mm and the back 10mm. The car now sits level as all corners measure the same. Note the car has only been driven about 20kms from getting done and should settle down over the next few weeks.

From my short stint in the car after picking it up, the ride seems slightly better than from the factory. This is a big plus because in my previous models lowered springs meant a "stiffer" ride. Seems not in the VE chassis.

A word of warning about wheel alignments - get your VE checked from new, they can be out from factory. Mine had a "Total Toe" of +7.0mm (checked before springs went in) which is quite a bit and could have caused premature wear on the tyres. The "Total Toe" is now +2.0mm on the rear.

I also measured the clearance under the car -

Front bar - 140mm
Bar(?) under engine - 130mm
Exhaust about 1/2 way down car - 120mm (lowest point)

My factory measurements were as follows -
Just went out to measure my factory height, and with 3/4 tank of fuel the figures are -

Front - 400mm with about 50mm gap (2") to tyre (20 inch tyres)

Rear - 375mm with about 25mm (1") gap to tyre (20 inch tyres)

Cool.

So it looks like I will be buying 2 of each of these next year.

2954 SR Front Coil approx 40mm Drop. Ride Height W/16" wheels approx 595mm $85.00
2955 SR Rear Coil approx 45mm Drop. Ride Height W/16" wheels approx 585mm $85.00

I made an error in my earlier post, the fronts used were 2954 not 2944 part no.

pedders? hhhmmm... sounds interesting... would there be significant change as to the performance of the ride when you got your ride that low?

I can't say for sure but I'd imagine the ride wouldn't change much (except the ground clearance). They are springs designed for the application not just springs with a hacked off coil. If the spring rates are correct it shouldn't change a whole lot.

For $340 ($85 x 4 + tax) I'll take the chance, I can always change it back.

If you look in post #1 (http://g8gt.com/t2032/) it appears this guy has driven them with pedders installed.

Lowering helps to lower the center of gravity which helps reduce body roll, improves cornering, etc. I think cars are ok lowered but they dont come as low as the aftermarket springs because different people will chose the vehicle for different reasons, so GM had to find a medium with performance and still have a smooth ride. Thats why most all sport performance versions come lowered and with stiffer springs because its strictly performance driven.

Welcome to the PEDDERS USA NATION!

Lowered doesn't necessarily result in poor ride quality. Production vehicles must meet a wide range of criteria, some of which are not in the interest of the enthusiast. A Pedders Denali that has been lowered actually increased the speed at which it could travel over a test speed bump. OE coils bottomed out at 16 MPH with a full passenger load. After lowering it but using higher rate coils the same test speed bump with the exact same load tripped the On Star alert as a roll-over when we cleared the speed bump at 30 plus MPH. It still had not bottomed out, but we did end the testing at that speed.

A G8 Pedderised with a full bush kit, coils, dampers, sways and endlinks is an awesome ride. How would you G8 look with these on it?

We did a couple of sets for SEMA. These are the beginning and the end of the G8 coilovers in a polished finish. We expect they will end up in some one's show car.

There's a little Pedder's overload on this thread, there are other springs available...

Not that I don't like Pedder's but my ride is getting a set of H&R springs. They are such a nice ride and give the car a beautiful stance!

They are available now, and lower the vehicle 1.4 front 1.3 rear.This is the Sport Spring set (pt#50750)and come in at $369 list. There's a reason H&R has been the number one manufacturer for the past 8yrs. ;)

p.s. Nice ride jkgmh

glad im not getting one till 09' or gxp model shows up. i have used h&r on every car ive owned minus the cobra, i had fms race springs on it. h&r is a good brand to use, and i have always loved them because they offer one of the lowest drops around, without damaging ride feel. hopefully by the time i get mine ill know what brand offers the lowest drop.

chrish

I have also run them on every show car I have built and love the time and effort they put into design. The cool thing too is they focus on proper rating first, then ride height. They also have free-colis on their springs to keep the spring from moving in the cups which is a major plus.

Is .5" worth the price? I know my gp lowered over an inch and with adjustable struts, it was well worth the $900.

I think these cars look good the way they are. But maybe putting 20's on them would require springs for lowering. idk...

There will always be Pedders overload, becuase of our solution based approach to suspension and the supprt our Dealers provide in the forums. Pedders offers a fully integrated suspension solution for the G8 -- everything is tuned to match from bushes to coils to dampers to sway bars to strut mounts to endlinks.... You'll see the results on my personal G8 in April.

With a response like that I may just have to see if Pedder's wants to sponsor me!

p.s. I saw you guys at SEMA last year, sad to say I missed the Pedder's BBQ though. I think my buddy Mike H. may get me to come around to drinking the Kool Aid sooner or later...we shall see.

It is always about the test drive. Don't accept claims, charts and graphs provided by a vendor. Make them prove it. Get a test ride / drive. That is why we have Pedders Day Events -- when you ride / drive a Pedderised vehcile be prepared to open you wallet or check book. :gr_devil:

Oh trust me I know, I was the Sales Manager for a late-model Mustang suspension company called Maximum Motorsports. I know who "talks the talk and walks the walk" in our industry. Being third generation of an automotive family and having 17yrs. in the auto industry myself, I have my respective opinions. I only allow companies sponsoring my show cars that I feel "bring it" to the table, minus the fluff.

I wish I could discuss topics like these more in my column and blog but my writing is catered to the masses. I do at least let it be known whose products I believe in by utilizing their parts on the cars I build. It's nice to see P2P coming to full fruition in today's society!
