Thumbs up Specific Difference Between AP1 + AP2 Rear Susp.?

Very specifically, what is the difference between the rear suspension on an AP1 and an AP2?

When you read the car magazines, they say "revised suspension geometry". What does that mean, EXACTLY?

Is it just the bumpsteer issue?

If you install the bumpsteer kits that are available on the aftermarket, have you achieved the equivalent "revised suspension geometry" as found on an AP2? Or are there other differences?

Thanks,

I think it is just spring and shock rates with a different alignment.

If you look in the FAQ in the Introductions forum, there is a link to the differences between 03 and 04 - you can read the technical data and specific elements there.
Suspension & chassis:

- Rear control arms lengthened
- Spring changes: Front: Increased spring rate 6.7% Rear: Decreased spring rate 10%
- Stiffened cross-members, joints and bulkheads increase torsional rigidity
- Steering rack ratio increase slightly to reduce high-speed nervousness
- Steering Gear Ratio now 14.9:1 from 13.8:1 - tuned to match new tire size
- Rear sway bar thinner
- Upgraded brakes incorporating an ABS system that features yaw control logic
- Brake pads redesigned

Thanks for the info!

Are the longer rear control arms retrofittable to the AP1?

Or do the bumpsteer kits achieve the same thing as longer rear control arms?
