STealthwerx Norwich- TRS Performance Dealer - Norwich

I.was really impressed with Gareth and the STealthwerx team. Super knowledgeable, friendly, honest and attentive.
As well as doing the Cambelt etc I went in for, they did a full.healthcheck; going above and beyond, looking thoroughly over the car making notes and recommendations on how I can improve things.
It's actually encouraged me even more to get another Fiesta ST with how infectious the enthusiasm is there for the little car.
The icing on the cake is that I think they're good value for money too.

Absolutely 11/10 service from the first point of contact.

I purchased a Fiesta ST200 with a knocking engine and was promptly accommodated with a booking for a diagnosis/health check to find a cracked piston and much more damage - with proof!

I was given some realistic and great advice that it wasn’t worth rebuilding the engine financially but to source a replacement.

Once I found a replacement Gareth was kind enough to allow me to have the engine delivered to him and got booked in to have it replaced.

Despite any staffing issues, Gareth made it a priority and made sure my car was completed and health checked/road logged in a timely manor ready for me to collect whilst going the extra mile suggesting stock software for longevity in this case.

I’m planning more visits with another vehicle in the future and would recommend anyone debating booking in, to do so.

Had to drop a review here. First time there and I went in for a health check due to failed emissions. A few issues picked up very promptly and I was informed. Spark gap was too small so that was fixed. Corroded pins on post lambda fixed. The car had hesitation in first and second gear and that has completely gone now. Good price also!

I've been to see Gareth a number of different times now and each and every time he's done an amazing job. I wouldn't trust any other company with my vehicles. Gareth and his team go above and beyond for their customers.

I travel from Kent to Norwich and it's definitely worth the journey. If you need anything doing to your car definitely travel to here!

There isn't anything Gareth can't do from a basic service to a full on stage 3 package with all the goodies and anything in between. He even does paint or bodywork should you need it.

I recently reached out to Stealthwerx to have a hybrid turbocharger and supporting hardware fitted to my mk7 Ford Fiesta ST, and I must say that my experience with them has been nothing short of exceptional and certainly worth the 7 hour round trip up to Norwich.

I contacted them with a pretty basic goal of what I had in mind - somewhat stealthy looking, quiet when you want it to be while making all the right noises when it should.
I've experienced it all before where over the top mods ruin a car and can make you start to dislike driving it.
You'd think this would be the case here, giving a car 140hp more than it came out the factory with wouldn't you?

Well that couldn't be further from the truth, resisting the urge to drive round for fun is now even harder than it was while being just as enjoyable and tame on the daily commute.

Initially I was worried the Miltek race non res they'd recommended was going to be too loud. However Gareth assured me it would suit my preferences perfectly.

Thankfully I'm delighted to report that he was spot on with what I wanted.
Sounds no louder than the stock car at idle / low rpm (happy neighbours), with 0 drone what so ever on the motorway.

The car performs just as they'd promised, I'm not sure a normal driver would even notice the difference in drivability from stock, if anything it's an improvement with better low down throttle response.
It's not until you put your foot down that the car becomes an absolute weapon.

The installation itself was carried out with precision and attention to detail.
It was evident that the people at Stealthwerx are not only skilled but also passionate about what they do.
This is no "map and dash" operation; they thoroughly examined my vehicle's health before upping the power, even inspecting the cylinders for any cracks in the walls.

Various pre-existing issues with the car were immediately highlighted to me, from where the last owner had (poorly) modified it in the past.
The workmanship was of the highest quality, and they ensured that every supporting component was properly integrated, while resolving all the issues found, leaving no room for compromise on performance or safety.

Throughout the process, the communication from Stealthwerx was brilliant. They kept me informed at every step, providing updates on the progress and answering any questions I had promptly. This level of transparency and customer engagement added to the overall positive experience.

Overall my experience with Stealthwerx was fantastic. Their commitment to delivering exceptional service and results is evident in every aspect of their work. If you're a Fiesta ST owner (other cars are available) looking to enhance your vehicle's performance, I wholeheartedly recommend reaching out to Stealthwerx. They are a extremely trusted name in the Fiesta community for a reason, and I couldn't be happier with the outcome of their work on my car.

A big thank you to Gareth and the team.

I visited Stealthwerx on the 25th for the first time based on a friends recommendation and the reviews I've generally seen from the owners clubs. From the moment I contacted Gareth prior to coming he was extremely helpful unlike one or two others that I had contacted for quotations/advice prior. He did not push for a sale but made recommendations based on the years of experience that he has with these cars. I booked in for a hybrid turbo fitting/mapping along with a full service, I was kept up-to date all through the day on progress and he was able to rectify a couple of little issues that came up and advised on some future changes that would benefit the car. Although the cars on a higher miles of almost 110k Gareth has transformed the car and done so safely.

I would highly recommend a trip to Stealthwerx for any automotive work, they're a friendly bunch and the prices are reasonable too.

Thanks again

Couldn’t recommend high enough.

Gareth’s seriously knows his stuff with the fiesta ST platform, I am now on my second fiesta st tuned/set up by stealthwerx.

Totally changed the performance, drivability and handling of both vehicles, speak to Gareth and find out the true potential within your car, and have no fear this is a trust worthy, reliable knowledgeable place to take your car.

Would definitely recommend anyone to take their car to Gareth, took a 3hour trip for TRS stage 2. During the 1st runs post mapping Gareth logged the car and noticed a few things he wasn’t happy with. He quickly rectified these issues and sent me on my way with a car much better! The level of care and passion for his business is noticeable and this reflects in his good reputation.
