What modifications do you carry out?

Suspension upgrades, brake upgrades, exhaust systems, wheel and tyre changes, and performance tuning. If you're after something else, ask, we have connections across the trade even when a job sits outside what we stock ourselves.

Do you work on my make of car?

We work across the same range as our servicing side, including Audi, BMW, Porsche, Aston Martin and most major manufacturers. Get in touch if you're not sure.

I know I want more from my car, but I'm not sure what to change first.

That's a normal starting point. Talk it through with us and we'll advise honestly on what will suit your car and how you actually drive it, rather than upselling the most expensive option.

Can I supply my own parts?

Yes, we're happy to fit parts you've already sourced, and to advise on parts before you buy them if you'd rather check with us first.

How long does modification work take?

Depends on scope. Straightforward tuning work can be same-day. Suspension or brake work usually needs longer, we'll give you a clear timeframe once we know what's involved.

Our approach

We treat modification as engineering.

A car is a set of systems working together. Change the suspension without thinking about the brakes, or tune the engine without considering how it puts the power down, and you can end up with something that's faster on paper but harder to drive well.

We look at the car as a whole before we touch anything, and think about how you use it day to day. A setup that's right for a track car isn't necessarily right for one you drive to work, so that's a conversation we have before any parts go on.

The answer

The same mechanics who service your car do the modification work too.

Dorrington approaches modification work the same way it approaches main dealer recorded servicing: understand the car properly before touching anything. The same mechanics who service Porsche, Aston Martin, Audi and BMW to manufacturer standard are the ones fitting your aftermarket parts. They already know how the standard car is meant to behave, which is how they know whether a change will suit the car.

What you get:

Mechanics who know your car before they change it
Every change set up to suit how you drive the car
The same standards used for main dealer recorded servicing
