A simple steel monocoque underpins the
R53 Mini
, to which is attached MacPherson strut front suspension with coil springs and an anti-roll bar. At the back, there's a multi-link set-up with coil springs, shock absorbers and anti-roll bar.
Standard 16s often switched for 17s
The brakes are 276mm vented front discs, with 259mm discs at the back. An anti-lock braking system is standard on all S models and derivatives, as is ESP traction and stability control. Brake pads and discs last for around 25,000 miles and wear evenly front and rear, so a whole new set of discs and pads will set you back around £500 including labour at a main dealer. Some owners fit uprated pads and discs, especially for track driving, as the standard kit is only just up to the job.
Wheels for the S are 16-inch alloys as standard and there was the option of upgrading to 17-inch wheels. Tyres are 195/55 R16 or 205/45 R17, both with runflat tyres fitted as standard from the factory.
Runflat tyres are a constant source of discussion among R53 owners as many feel they compromise the ride, handling and steering of the car. At £140 per tyre to replace a runflat with a new one, many owners opt to fit standard non-runflat tyres and report marked improvements in ride comfort, turn-in to corners, cabin refinement and steering response. If you ditch runflats, just make sure you carry a can of tyre sealant in case of a puncture.
Check for worn ARB links at the front
The power steering pump of the R53 Mini makes a distinctive high pitched noise when the car is at a standstill. It's nothing to worry about and just the electric steering pump working. More worrying is a bump caused by a worn universal joint, so listen out for this as it's a costly procedure to replace.
Other knocks or noises from the front suspension are likely to be worn anti-roll bar links, while at the rear the top suspension mount bushes are worn and need renewing.
The Mini Cooper S Works GP has unique aluminium rear control arms that save 15kg from the weight of a standard S. It also has unique four-spoke alloy wheels that reduce unsprung weight by 2kg per corner, while the GP's suspension sits 10mm lower than an S model's. Mini also fitted firmer springs and dampers, though it left the anti-roll bar unchanged.
PHer's view:
The regular R53 brakes aren't quite up to the job when matched with the approx 200 HP from the works engine upgrade.
