Hello 👋🏼

I’ve been using mini torque since I bought my first Mini, a Pepper White R58 Cooper S Coupe, last March and decided it’s probably time I actually joined in.

I’ve gathered quite a lot of knowledge over the last year or so, and have ended up doing far more to my coupe than I had planned...

I’ll include some of the list of modifications...
  • Manic Stage 1 Remap (from Lohen), last dyno'd @ 240bhp & 390nm with only the map and cat-back exhaust (lots done since...)
  • RSIC6 Wide Arches
  • JCW 4 pot brake upgrade & Hel braided lines
  • BC BR Coilovers & Adjustable Rear Control Arms
  • AEM Induction Kit
  • Airtec larger FMIC
  • 200 Cel Sports Cat and custom non-res cat-back exhaust
  • Forge VTA BOV
  • Cobra Nogaro Fixed Bucket Seats with Schroth ASM Harness
  • Custom Suede Interior Trim, JCW Carbon Handbrake & Gear Knob, JCW Alcantara Steering Wheel
  • JR Wheels
  • Rear Spoiler and Custom ETS Racing Challenge Diffuser
  • The usual dechrome and bigger scoop, oem black line rear lights
To be fitted (and painted first..):
  • Heigo coupe roll cage
  • DuellAG front bumper
  • Oil Catch Can kit (PCV side only)
I've done all the work to the car myself, except for the remap (obviously) and have enjoyed every (ok most, except changing the cat, that heatshield is a pig) minute of it! It's definitely taught me a lot, and has sparked a serious (but expensive) passion for cars and tinkering.

Here's some pictures of 'Martin' (named after the very shortlived martini livery)..

And here's a before photo of when I bought it, for fun... 🤪

I look forward to participating in some discussions, and hopefully I'll be able to help people on this forum as they've helped me!

Welcome to MT. That's a really nice R58 😎
On the first pictures the spoiler does look a bit odd but I think because of the angle of the pictures.
Thank you 😊

I guess the angle doesn't make it so clear.

But I think people forget the point of a spoiler is to spoil air from the back end of the car, not necessarily to cause downforce. The angle totally depends on the car, and guessing that it should have more rake with no testing, is a bit silly. I'm no aerodynamic expert either - but I didn't stick it on the back of my car without doing my research, as per every other modification i've made 😅

Well I'm sorry you don't like it, can't please everyone 😌 It's just a shame that on the first thing I ever post, people are straight in with the criticism 🤣 I've spent many hours working on this car, how about picking a good bit rather than pointing out a 'negative' .... especially when it isn't even a fault but rather how it is actually meant to be.. 🤣

Good morning Martin,

You look great chap, your owner has done a terrific job on you. Question though, if you were just starting out on a project like yours, would you begin with a Stage 1 remap or Stage 2. Based on that decision, what made you choose Lohen over the others that are available?
Once the remap was chosen, did you see a considerable change in performance on the car without the other mods?
I prefer my cars to look normal but have all the upgrades under the bonnet, so happy to do the engine, brakes and exhaust system as long as it did not change the outside look.
Just out of interest, where did you source your components and why did you choose them?
Car looks fantastic, Martin you should be happy and your owner very proud.
Thanks for your reply and information.

Hi! Thank you very much!

I'm running a stage 1 remap, and in all honesty, can't imagine needing any more power. It might get another 10/20 odd bhp from a stage 2, but whether I would ever even use it is another question - plus, as it stands, torque steer is a bit of an issue, and I do find it to be a bit of a handful when i'm flooring it. I'm looking into ways to resolve/reduce this at the moment.

When I first had the remap with only the panel filter and cat-back exhaust, the car was truly transformed with the extra torque to 390nm, however it did run at 205bhp and 284nm of torque without the remap with just those modifications.

I went with Lohen because of their reputation, and at the time they were offering Manic maps. Lohen were great and have since offered me plenty of help and advice on other topics, they're a great bunch of guys! The remaps they offer now have had plenty of great feedback too.

In terms of why I chose certain parts, well it's down to many, many, many hours of research through forum threads, facebook etc and also by contacting some of the specialists like Lohen. Take it all with a bunch of salt, though, I'm not really a believer in buying a brand name just for the sake of it, when other high quality products exist for less of a premium elsewhere - remember these big brands need you to pay for their sponsorship and marketing bills...

My exhaust for example is custom made by a company called Pro-speed in Cardiff. Charlie spent many hours on it and achieved just what I wanted - it's a non-res with a tiny back box - and looks identical to the R56 challenge exhaust.

If you have any other specific questions, feel free to ask or drop me a message :)

you'll no doubt help torque steer with front lower arm rear bushes changed to Powerflex black series or similar firmer options and the addition of an ATB differential like a Quaife or MFactory etc, at 390nm you won't likely resolve it but you will make a big improvement. If you have aggressive front camber it probably won't help (lower than -2.0 to -2.5)....

I think I'd lift it rather than have high speed compression fouling, it does look tidy and still would a little taller no problem

upgrading bar's'? I'd hope that means reducing the front or removing it, aware some larger bar options exist but you don't need that at the front,

the diff will transform the car, with both I'm sure you'd never look back, it'd be the best ~£1500 spent quite possibly, other than if converting the final drive😁

I'd quite like one of these I have to say, always liked the look,

only a matter of time before someone does a slightly wider body conversion, they'd carry it off rather well I think

nice isn't it, I'd run one, if there's headroom haha, I think all MCS's look good in Pepper white anyway really, mods haven't taken this too far like some cars
