What Our Customers Say
Real feedback from real drivers who trust Wallace Performance with their cars.
"Wallace Performance remapped my Astra and the difference is night and day. Throttle response is instant, power delivery is smooth, and the car pulls hard right to the redline. They even did a before-and-after dyno run so I could see the numbers. Honest, professional, and seriously know their stuff."
Sarah Jenkins
Vauxhall Astra VXR Owner — ECU Remaps
"I brought my M3 in for a full geometry setup before a track day. The laser alignment was incredibly precise and the car felt completely different on the road — sharper turn-in, more stable under braking, and tyre wear has been perfectly even since. Worth every penny."
Michael Davies
BMW M3 Competition Owner — Laser Wheel Alignment
"Had a custom exhaust built for my ST and it sounds absolutely perfect. Not too loud on the motorway, but when you put your foot down it turns heads. The fabrication quality is top notch — TIG welds are beautiful and it fits like a glove. Wallace Performance is now my go-to garage."
James O'Connor
Ford Focus ST Owner — Custom Exhaust Systems
"My TT had a persistent check engine light that two other garages could not figure out. Wallace Performance diagnosed it in under an hour — a faulty coil pack and a dodgy sensor. They fixed it same day and the car has been faultless since. Proper diagnostics, not guesswork."
Emma Richardson
Audi TT Owner — Fault Diagnostics
"Rolling road session was brilliant. The dyno graph showed exactly where my power was dropping off and the team explained everything in plain English. We tweaked the boost and fuelling on the spot and gained 23bhp. You can't argue with printed proof."
Tom Bradley
Subaru WRX STI Owner — Rolling Road
"After lowering my Golf, the handling felt vague and my tyres were wearing unevenly. The four-wheel alignment sorted it completely. They set custom geometry for my coilovers and gave me a before-and-after printout. Car drives like it is on rails now."
Rebecca Holt
VW Golf GTI Owner — Four Wheel Alignment
