CATERA SUSPENSION UPGRADES - Part 1

UPDATED: 7-4-09
The Catera's front control arm bushings are prone to tearing from either or both, "wear & tear" and improper installation. When they tear the wheels lose alignment (both camber and toe-in) and tire wear increases. A re-alignment is useless as the damaged bushings will cause the wheels to misalign once the car is traveling.
Bob Chen, an Omega owner, found that bushings from the 1989-1995 BMW M5/E34 use a stronger rubber compound that resists tearing. These M5 bushings are also slightly firmer than the Omega's original GM ones. They fit in place of the Omega's front/horizontal control arm bushings. Omega bushings are identical to Catera bushings.
While the rubber M5 bushing is an improvement over stock, there is something better. Polyurethane bushings for the BMW M5 will fit in place of the Catera's front/horizontal control arm bushings. Polyurethane bushings resist tearing better than rubber ones. They produce less friction thereby reducing the effort needed to pivot the control arms when the tires encounter rough road surfaces. Because of this they allow the struts to absorb more of the road shocks instead of transmitting them to the chassis. Poly-bushings also hold their characteristics much longer than rubber bushings, greatly reducing maintenance. They maintain wheel alignment much better during cornering, and when braking loads are applied.
Polyurethane bushings will improve handling. Rubber bushings flex and compress during braking, and in response to steering inputs. Polyurethane bushings don't compress as much as rubber ones. With poly-bushings there is less compression delay so the car turns almost instantly. Two issues. They might allow more road noise to reach the interior, and there are no polyurethane alternatives for the rear/vertical control arm bushings.
The Catera uses a unique rear/vertical bushing in the front control arm. Inside is a ball-joint type insert, lubricated by silicone fluid, that pivots under braking. This specially calibrated bushing improves control by introducing more toe-in at the wheels under heavy braking. It improves directional stability. This toe angle change at each front wheel also helps when braking in patchy conditions (dry pavement one side and water/ice on the other). So far there are no alternatives to stock.
I suggest replacing the control arm Ball Joints when replacing the bushings regardless of whether you replace the control arms or not. They have the same mileage as the bushings and are just as worn. The original Ball Joints are riveted on. These rivets will need to be drilled out. The replacement Ball Joints bolt in place.
An alternative to replacing the bushings and ball joints is to replace the control arm assemblies. New control arms come with stock bushings and ball joints installed. You must remove the old control arms to install new components anyway. Replacing the whole assembly saves the time and cost of buying the bushings and ball joints plus the time and labor to have them installed on the old control arms. New control arms aren't cheap but they are quicker. If "time is money" to you then it might be worth it.
Aftermarket Camber Adjustment Bolts increase the range of adjustment over the stock bolts. They allow fine tuning of the front wheel alignment. This helps reduce the tire wear on the inside edge of the front tires common to the Catera whether using lowering springs or not. If your car is lowered, these eccentric bolts are a must.
The Catera's rear suspension's semi-trailing arm bushings are rubber. Braking pulls the wheels back as momentum pushes the car body ahead. Due to the elasticity of these rubber bushings, the rear wheels will toe-out, encouraging oversteer. Stiffer polyurethane bushings resist this distortion so the wheels track truer. Stiff bushings equal better wheel alignment and less tire wear. Eccentric poly outer bushings also help correct camber on lowered cars. There are also eccentric poly inner bushings to adjust rear toe.
Of course it takes more than stiffer bushings to make a Catera handle like an M5. Below is a list of suspension components I found for the Catera. Most are sport upgrades. Any suspension part made for the Omega will fit the Catera. Stock GTO front & rear springs and rear shock absorbers will fit the Catera, but the front struts will not. GTO front wheel hubs are different from the Catera's. That's why the struts won't fit. The Pontiac GTO/Holden Monaro use the same IRS bushings as the Omega/Catera and aftermarket bushings for their IRS will fit them as well.
Be warned. Some of this is guess work. I'm assuming aftermarket GTO springs and rear shocks will fit. There's no good reason they shouldn't but I feel I must warn you. Same goes for the BMW front and Holden rear bushings. I trust the good reports from owners using these parts but that's me. I suggest you search the forum and make up your own minds.
WARNING: All these parts will fit assuming you are using stock sized wheels and tires. Wider than stock tires on stock sized wheels (Standard or Sport) might rub performance struts/shocks and springs. The wheels must also have the proper 35mm - 45mm offset.

INSTALLATION TIP: For rubber bushings, DO NOT torque the control arm bushing nuts & bolts until the car is lowered to the ground. The rubber will be pre-stressed when the car is lowered to the ground, increasing the chances of tearing. Polyurethane bushings can be torqued while the car is raised. Urethane is "slippery" and will pivot rather than tear.

Eccentric bolts to increase camber range for the front wheel alignment.
WHEEL SPACERS - Not technically a suspension upgrade but many of you want wider rear tires. Wheel spacers will keep them from rubbing the springs and struts/shocks. They provide a wider track for more stability in the corners. H&R Wheel Spacers - Bolt Pattern 5x110 / Hub Center 65mm [Saab 9-3, 9-5, 900 (5 lug)]
5mm DR Spacer - #1045650
15mm DR Spacer - #3045650
20mm DR Spacer - #4045650
25mm DRA Spacer - #5045650
http://autosportstyle.com/shop/wheel-spacers-c-147_965_1004.html?filter_id=47&sort=2a
I used 25mm to bring my Catera Sport's 235/45-17" rear tires closer to fender lip for a wider track. The spacers fit perfectly and the tires don't rub the fender lip.
SPECIAL MENTION
Pneumatic Suspension - An alternative to the firmer sport ride. This kit provides the cockpit adjustable height and a softer ride preferred by lovers of cruising and low riding.

INSTALLATION TIP: For rubber bushings, DO NOT torque the control arm bushing nuts & bolts until the car is lowered to the ground. The rubber will be pre-stressed when the car is lowered to the ground, increasing the chances of tearing. Polyurethane bushings can be torqued while the car is raised. Urethane is "slippery" and will pivot rather than tear.

MISCELLANEOUS
Homemade Bearing Tool (Removal/Installation)
http://www.youtube.com/watch?v=GJ5FkOoT5QE
Simple homemade tool to pull the bushings out & in.
Ingalls Engineering Camber Adjusting Bolt: part # IEC-I-81260
http://store.summitracing.com/partde...D81260&FROM=MG
Eccentric bolts to increase camber range for the front wheel alignment.
WHEEL SPACERS - Not technically a suspension upgrade but many of you want wider rear tires. Wheel spacers will keep them from rubbing the springs and struts/shocks. They provide a wider track for more stability in the corners. H&R Wheel Spacers - Bolt Pattern 5x110 / Hub Center 65mm [Saab 9-3, 9-5, 900 (5 lug)]
5mm DR Spacer - #1045650
15mm DR Spacer - #3045650
20mm DR Spacer - #4045650
25mm DRA Spacer - #5045650
http://autosportstyle.com/shop/wheel-spacers-c-147_965_1004.html?filter_id=47&sort=2a
I used 25mm to bring my Catera Sport's 235/45-17" rear tires closer to fender lip for a wider track. The spacers fit perfectly and the tires don't rub the fender lip.
SPECIAL MENTION
Pneumatic Suspension - An alternative to the firmer sport ride. This kit provides the cockpit adjustable height and a softer ride preferred by lovers of cruising and low riding.
StreetRidePro - Air Spring Suspension w/compressor, solenoids, hoses, etc. #FBS-CAD-04-KIT3
