Ultimate Guide To VW Golf Mk8 Modifications

Believe it or not, the VW Golf Mk8 has been kicking around for four years now so, inevitably, there is quite a selection of modifications available on the aftermarket. Here are some of the best we could find…

When it comes to performance variants of the VW Golf Mk8, generally you have the ‘lower output’ GTI version (running the 2.0T EA888 EVO DRNA 240bhp engine) and the ‘higher output’ R model (2.0T EA888 EVO DNFG 316bhp).

When we spoke to the guys at Revo, they told us the main reason they separate the two models is that, unlike the Mk7 GTI and R, the Mk8 variants use turbos produced by totally different manufacturers meaning aftermarket parts – like air intake systems etc. – generally aren’t interchangeable between the two. You have to wonder whether Volkswagen did that on purpose to make life harder for tuners?

Clamping down on ECU tampering

Wolfsburg certainly didn’t want anybody playing around with the car’s engine control unit that’s for sure. As of yet, we’re still to hear of a tuner that has cracked the encryptions on the VW Golf Mk8 GTI/R’s ECU, but that hasn’t stopped global tuners powering on with the development of a whole host of other hardware for the eight generation car in preparation for the software to eventually roll out. I guess that explains what this feature is all about…

BMP Tuning are an impatient bunch and couldn’t wait for off-the-shelf software to become available, so adapted a JB4 piggyback ECU from Burger Motorsports to uncork its GTI’s 2.0T and, with the help of some of the add-ons you’ll find in this VW Golf Mk8 modifications guide, managed to increase power to 321hp and 350lb/ft – making it arguably the most power GTI in North America, if not the world… You can check out BMP’s 321hp GTI here.

In terms of software, it’s very much not a case of if but when somebody does eventually crack the code, so this feature will give you an idea of the parts you need to get in place before remapping your ECU and reaping the benefits of the solid foundations you have put in place.

Please note that many firms we spoke to are in the R&D stages of their Mk8 Golf tuning programs, so either have new parts about to launch or very close to production stages. Thankfully, many chassis parts are interchangeable between the MQB Mk7 and the Mk8, meaning many companies are able to offer the same hardware parts from their Mk7 MQB range for the 8th gen. Of course, a few firms have been super efficient and already produce a range of Mk8 specific parts.

While it feels like more than ever the government and car manufacturers in general are trying to prevent us from modifying and personalising our cars, it’s very exciting to see just how many companies are getting involved with VW Golf Mk8 modifications.

Brit Wagstaff at Milltek told us these systems are now being manufactured in Milltek’s ‘Advanced Manufacturing Centre’ utilising some of new equipment including Tube & Sheet Laser, All Electric CNC 4” Bender & 3D Laser Cutting Robotic Cells to allow for precise engineering.

Apparently large bore downpipes have also been developed for the Mk8 which come with either a High Flow Sports Cat (£955.18) or Race Cat (£784.61). While a de-cat pipe isn’t currently available we can’t imagine it will be too long until one is.

RPI Equipped

Canadian firm RPI Equipped might not manufacture any of its own products, but its demo VW Golf R Mk8 looks so mighty fine that we simply couldn’t leave it out. To think this car is only a set of (well fettled) wheels and suspension, goes some to show you want a good looking car the Golf R is. However, as we all know, everything looks better with a reduction in ride height and a larger diameter wheel. The car you see here feature H&R Street Performance coilovers ($2195.00 cdn), H&R EBM Electronic Bypass Module ($595.00 cdn), H&R 26mm/24mm anti-roll bar kit (825.00 cdn) and, the icing on the cake, Rotiform TUF-R wheels ($425.00 cdn) in 8.5×20” Et40 fitment.
