Performance Car Parts Categories Understanding Exhausts, Cooling, Suspension and Handling Upgrades at Gravity Performance
An overview of how Gravity Performance, a UK performance parts specialist trading since 2004, organises its catalogue across exhaust systems, cooling upgrades, suspension components, and body styling parts.
Modifying a road or track car tends to fall into a handful of recognisable categories, each aimed at a different part of how a vehicle sounds, breathes, cools, handles, or looks. Gravity Performance is a UK-based supplier that has organised its catalogue around exactly these categories, stocking everything from downpipes to coilover kits. This overview walks through the main groups of parts on offer and where each one fits into a wider build.
What Gravity Performance Sells: A 20-Year-Old UK Performance Parts Specialist
Gravity Performance has been trading since 2004, which places it among the longer-established names in the UK aftermarket parts space. The company describes itself as a specialist in performance and tuning parts for road and track use, with a catalogue that spans exhausts, cooling, suspension, and body styling rather than focusing on a single niche. Its shop lists thousands of individual items across dozens of categories, from air induction kits to wheel spacers, all stocked in a UK-based warehouse.
Exhaust Systems and Downpipes: From Catback Exhausts to Decat Conversions
Exhaust work is one of the more visible categories in the range, covering catback exhaust systems, decat downpipes, sports cat options, and DPF delete downpipes for diesel applications. A catback exhaust system replaces everything from the catalytic converter back, while a decat downpipe removes the catalytic converter section entirely for a more direct exhaust path. Examples in the Gravity Performance catalogue include a catback exhaust system for the BMW Mini R53 Cooper S, a 3-inch catback exhaust for the Audi TT MK1 8N 1.8T 225, and decat downpipes for applications such as the VW Golf MK6 R and Audi A3 8P S3. DPF delete downpipes are also stocked for diesel-engined BMW models including the 1 Series N47 and 3 Series N47 ranges, alongside separate listings for exhaust manifolds, back boxes, tips, and resonator deletes.
Cooling Upgrades: Intercoolers, Radiators and Engine Temperature Management
The cooling section is built around the idea of keeping a turbocharged or hard-driven engine within a reasonable operating temperature. Intercooler kits cool charged air coming from the turbo, and the range includes Direnza intercoolers designed for tuned and turbocharged setups, as well as a front mount intercooler listed for the BMW 5 and 6 Series E60/E61/E62/E63 built between 2003 and 2010. Twin-core aluminium radiators are positioned as an upgrade over a factory radiator, with listings such as a 40mm high flow radiator for the Toyota MR2 SW20 2.0 and a 40mm high flow radiator for the Vauxhall Astra H MK5 2.0 VXR. The cooling category rounds out with radiator cooling fans, silicone hoses built with a 5mm thick wall, and oil coolers, each addressing a different part of an engine’s thermal management.
Suspension and Handling: Coilover Kits, Lowering Springs and Adjustable Suspension Arms
Handling upgrades sit in their own section of the Gravity Performance site, with adjustable suspension arms offered for tuning suspension geometry and restoring factory alignment parameters. Bilstein coilover kits are listed for adjustable ride height and road feedback, while lowering springs are described as using progressive spring rates to drop ride height and centre of gravity without necessarily sacrificing comfort. Drop links with polyurethane bushes are stocked to support anti-roll bar performance on lowered vehicles, and Direnza wheel spacers are offered as hub-centric spacers intended to widen the track of a vehicle. Together these parts form a handling-focused counterpart to the cooling and exhaust ranges, aimed at the geometry and stance of a car rather than its airflow or temperature.
Aero and Body Styling: Bodykits and Visual Performance Enhancements
Styling parts make up a further category, including aero bodykits, front bumpers, front splitters, side skirts, spoilers and wings, canards, rear diffusers, bonnets, grilles, and mirror covers. One example from the catalogue is an M3-style body kit for the BMW 3 Series F30 built between 2012 and 2019. This part of the range covers both aerodynamic components such as splitters and diffusers and purely cosmetic items such as sunstrips, decals, and LED grilles, reflecting the breadth of the Body Kits and Body Styling listings on the Gravity Performance shop.
How Gravity Performance Stocks and Supports Performance Builds
Stock is held exclusively in a UK-based warehouse, which the company states is intended to avoid import duties and keep the listed price as the price paid at checkout. Customer support is handled by an in-house team described as having over 30 years of combined experience, available to answer compatibility questions and build-related queries by phone or online contact during weekday office hours. Payment options include major debit and credit cards along with finance through Klarna, Clearpay, and PayPal Finance on selected products. Many items ship with fitting instructions where applicable, though simpler accessories are described as suited to straightforward self-installation.
The breadth of the catalogue means most builds touch more than one category at once, since an exhaust change is often paired with cooling or suspension work on the same vehicle. The following list summarises the main groups a buyer is likely to encounter when browsing the range:
- Exhaust parts include catback exhaust systems, decat downpipes, sports cats, DPF delete downpipes, and exhaust manifolds.
- Cooling parts include intercooler kits, Direnza intercoolers, twin-core aluminium radiators, cooling fans, silicone hoses, and oil coolers.
- Suspension parts include adjustable suspension arms, Bilstein coilover kits, lowering springs, polyurethane drop links, and Direnza wheel spacers.
- Body styling parts include aero bodykits, front splitters, side skirts, spoilers and wings, canards, rear diffusers, and LED grilles.
Across these groups, the common thread is a catalogue organised by function rather than by a single flagship product, letting a build be assembled from distinct exhaust, cooling, suspension, and styling choices as a project develops.
