G-Spot Tuning & Mods is a full-service garage, not just a tuning shop. Alongside ECU remapping, we cover diagnostics, suspension, exhaust fabrication, and everything in between — all with the same obsession for quality.
We run full electronic diagnostics on any vehicle before any work starts. No guessing, no parts-swapping hoping for the best — just a clear picture of what's happening and a straight answer on what it needs.
Only quality diagnostic equipment and parts are used throughout. If it's not right, it doesn't go on the car.
Aftermarket suspension fitted and set up properly — not just bolted on and sent out the door. We carry out full 4-wheel alignment after any suspension work to make sure the car handles as it should and the tyres wear evenly.
For race and rally builds, we offer full competition suspension set-up: corner weighting, bump stop tuning, and geometry dialled in for the circuit or stage you're running.
No off-the-shelf fitment issues — we fabricate custom exhaust systems from scratch, built around your car and what you want it to do. Whether that's a straight-through track system, a cat-back upgrade, or a full manifold-back build, it's made to measure.
DPF and AdBlue issues are among the most common faults we see on modern diesels. We diagnose the root cause first, then offer the right solution — whether that's a forced regeneration, a quality replacement, or an off-road delete for competition use.
All solutions are discussed honestly. We won't upsell a fix you don't need.
Our MOT pre-check goes through all the key points an MOT tester will look at — lights, brakes, steering, tyres, emissions, and bodywork — so you know exactly what state the car is in before it goes for test.
Anything found gets quoted and fixed before the test where possible, saving you a retest fee and the inconvenience of a failure.
From routine mechanical work to one-off custom fabrication, we cover all aspects of vehicle mechanics. Servicing, brakes, clutches, cooling systems, engine work — if it needs doing, we can do it.
We also take on custom fabrication projects: roll cages, custom bracketry, bespoke parts and one-off builds. All work is carried out to a high standard using quality materials and parts throughout.
