Welcome to RKM Motorsport. Formerly RVV Motor Works, one of the top tuners from Gran Turismo 4, we’re continuing our service in Gran Turismo 5, under a fresh new name. Our main aim is to produce high quality tunes that can be driven anywhere by anyone. From the Prius to the McLaren F1, we can tune pretty much anything that can be tuned. The Tunes The name's Kyle. On my own time, I tend to build cars that remain street legal but will knock the teeth out of purpose built race cars on Sunday. The rest of the time my main goal is to make customers happy regardless of what that means dealing with. Yes, that includes you over there in the corner with your Fiat 500, and you over there with your overweight Renault, err, Nissan GT-R. ~Kyle My Tunes: I’m Rojer, but Roj is what I go by most of the time. I tune cars to punch way harder than cars above their league do, whilst keeping them fun and easy to drive. I usually tune cars up to around 400bhp on sports tyres, but I try to keep a large, varied range of tunes. If you can’t find one that suits your needs, I can hook you up. ~Rojer My tunes: Hey there, I'm Sapphire and I'm the new girl. I tune whatever tickles my fancy or looks like fun, or is just something unique. And I never forget than fun is the most important part of driving, either! ~Sapphire My tunes: RKM Budget Builds 80k Camaro Are you a mobile user who can't use our image hyperlinks? Are you wondering where our old tunes went? Check the new Mobile-Friendly Hyperlinks and Tune Archives page. Request Policy We’re continuing our “1 review = 1 tune” offer. You review a car of ours from the above lists and in exchange, we’ll tune up a car for you. It's preferred you supply the car with all wanted parts already equipped but not 100% needed (may take more time if we have to buy + modify the car). If you're unsure what a review is, take a look at this, this and this. Hint hint. Videos accompanying the reviews are even better. We focus primarily on grip tunes. Drift and stunt tunes will be refused. We may also refuse certain cars or requests if they are deemed to be ridiculous or simply unnecessary. Below is the request form, just copy and paste it into a message and fill it in. Anything in brackets ( ) you may delete. Thanks!
