Audi B10 S5, SQ5
It doesn’t have a power problem. It has a driving problem.
What’s new for your B10
Four new ways to drive your B10.
The new S5 is fast and refined. It also carries about 500 lb more than the B9, and the factory setup leans on safe understeer. We rebuilt how it turns, rotates and grips: springs, sway bars and wheels developed as one system.
- The B10 chassis systemNew hardwareSprings, front and rear sway bars, and wheels that work together.
- B10 S5 lowering springsNew hardwareA level stance and firmer control, on your factory dampers.
- Front & rear sway barsNew hardwareTwo settings each, Cruise and Carve. The rear is tuned to rotate.
- iE × APEX VS-5RS wheelsNew hardwareA 20-inch monoblock built for the B10 alone.
New hardware
The B10 chassis system
Fixing a chassis, not selling parts.
No single part fixes the B10. Each piece solves a different part of the problem, and together they change how the whole car drives. Tap a part to see what it adds.
ControlLower ride height and firmer springs cut body movement and sharpen response.
RotationFront and rear bars rebalance the car so it turns in and rotates instead of pushing wide.
Contact patchB10-specific fitment puts more usable tire on the road.
All three: the complete transformation.
New hardware
Lowering springs
Drop it. Plant it.
A clean, level drop and a real handling upgrade. Lower, firmer and sharper, with rates matched to the factory dampers so the ride stays livable every day.
Drop25 mm front, 35 mm rear, for a level stance
Front rate405 lb/in
Rear rate628 lb/in
DampersFactory, adaptive (DCC)

New hardware
Front & rear sway bars
Wake up the chassis.
We didn’t reuse a B9 spec. Both bars are tuned for the weight the B10 actually carries. The rear is deliberately oversteer-forward, so the car rotates on command instead of plowing wide.
Front bar

Manages the heavier front end. Machined billet brackets and greasable zerk bushings.
Rear bar
Rotation on command
Trades factory understeer for a rear that comes around when you ask it to. Not a switch that snaps loose.

Cruise or Carve
Two settings on each bar, both stiffer than the factory setup. iE green powdercoat.
iE Front Sway Bar, B10 S5
iE Rear Sway Bar, B10 S5
New hardware
iE × APEX VS-5RS
Built for one car.
The B10 has its own hub and offset geometry, and no off-the-shelf wheel uses all of its clearance. We built one with APEX that does. The suspension was 3D-scanned so the VS-5RS uses every millimeter between the fender lip and the upper control arm, with zero rub and room for bigger brakes later.

For the B10 SQ5
Driving an SQ5? These fit too.
On the SQ5, lowering is done with links instead of springs, and it gets its own sway bars. These are the same iE parts B9 SQ5 owners already run, now confirmed for the B10.
