WEST COAST EDITOR MARK VAUGHN: The Dinan Signature Series S3-R BMW 1M coupe is like a brief, stubby, completely enclosed 4-seat go-kart.

The brief wheelbase and fairly quick suspension travel meant a stiff trip. Stiff, not jarring. Whilst there is small room for the even the stock BMW suspension to move up and down, what movement there is here is tightly controlled. The automobile by no means bottomed out when I had it, regardless of heavy inputs, and never ever felt like it was transferring shock loads straight into the chassis. It by no means felt like it was reaching the bump stops, even though with progressive bump stops, it may possibly have been doing it and it was so smooth it did not really feel like it. Even though much more suspension travel would have been favored, the dimension and form of the car prohibited it. The Dinan springs had been matched to the shocks completely. This was practically nothing at all like some other aftermarket setups that just lower the springs for that lowered boy-racer seem without bothering to match the shocks and bushings to the new trip height, leaving the bad dope who has to drive it to bounce along on the bump stops.

Also, the wheels at total crank did not ever scrape the wheel wells, yet another typical shortfall of aftermarket chop shops.

It had piles of energy and torque. Dinan now has 5 guys who do practically nothing but dig through BMW chips to locate the place they can tweak them. Computer software tuning is in which the further boost comes from. They not only got the wastegate to clamp shut a minor longer, but retuned the fuel mixture and ignition timing so it does not all go kablooie underneath load. Engine hardware consists of larger compressor wheels for the turbos, a Dinan intercooler and Dinan intake and exhaust. A bigger oil cooler helps guarantee engine longevity. The result is 444 hp at 6,350 rpm and 450 lb-ft of torque at 3,300 rpm. They are so confident in their operate that Dinan matches BMW’;s 4-yr, 50,000-mile warranty.

To get that electrical power to the ground and make it useable, Dinan also went through the suspension and modified almost everything except the back links (most of the back links, anyway). A total, adjustable coilover kit can lower the auto by as significantly as an inch with out generating it unpleasant in commutes. A front sway bar, spherical monoball front bearing kit and rear toe hyperlinks round out the bundle.

On normal roads at standard speeds, it is completely livable as a day-to-day driver. It really is even entertaining. Clutch pedal is usually BMW simple, with smooth engagement accessible to even the clumsiest left foot. Likewise throttle feel was linear. Los Angeles freeway hop was not a dilemma in this automobile, either, regardless of the fairly short wheelbase of the stock BMW.

Ideally you’;d want to consider this to a racetrack, 1 with a great deal of quick, tight turns. Unfortunately, the Autoweek West Coast personal test facility is still in development … in my mind. So I did the next very best point and took it to a deserted mountain road. Said road has a great deal of second- and third-gear turns, so many in fact that I wished for a shorter third or taller 2nd gear. If I was setting the automobile up for a hill climb here, I’;d have asked for a ratio modify. That is not Dinan’;s problem, however.

On hefty acceleration, torque steer from the rear wheels reminded me of the Beach Boys line about receiving pushed out of shape and currently being hard to steer. This a single swayed a tiny from side to side beneath full launch and you did have to right that with some steering input, but it wasn’;t what you could get in touch with “hard to steer.” You just have to pay attention.

The tires are massive-broad for a vehicle this little. Only a couple instances did the rears break loose exiting tight corners, and then the stability control grabbed them.

Most of the time I complain about sporty GT automobiles being as well lengthy to genuinely fit all around tight corners, although this 1 may possibly be a little also brief for these situations. Possibly 6 inches of wheelbase would even the auto out. Or maybe far more seat time would do it. Regardless, the auto is a blast on a mountain road. You can enter any corner with confidence and power out of it with glee.

Certainly this is the most overall performance anybody’;s ever going to get out of a BMW one-series and nonetheless be in a position to drive to the grocery shop with out being arrested. The 4 real seats and trunk make this a entirely sensible, useable day-to-day driver. The clutch was BMW-simple to operate, the shifter was exact and smooth, and the throttle was smoothly linear. It has all the trappings of a genuine automobile and significantly of the character of a track-day demon.

Now I would like to try a Dinan BMW 3-series, please.

ASSOCIATE WEST COAST EDITOR BLAKE Z. RONG: A few things occur when you step on the throttle of the 445-hp, Dinan-tuned BMW 1M. At 1st, absolutely nothing. For the very first couple of milliseconds the vehicle blinks and shuffles about a bit as if to request, “You certain about this, pal?” Then it spits forth a devastating crackle and revs to redline so speedily and so ferociously that the driver barely has time to hold up or shift — the rear end squirms and quickly gets whipped back into spot as if the traction handle was a Catholic school nun, its error light blinking on the dash like the lights at the Riviera. Wild cackling, this time from the driver, inevitably ensues. By then you’;re presently 5, 7 bus lengths ahead, halfway down the dragstrip, flying up that on-ramp onto the 710 Freeway, whatever fulfills your personalized efficiency metric…

To induce this level of antisocial, maniacal laughter, Dinan took the previously prized BMW 1M and upfitted larger turbochargers to it. Bigger compressor wheels and upgraded wastegates create 14 psi of increase at 6,300 rpm, in accordance to the reality sheet. Dinan employs an army of hackers to dig into the BMW ECU, recalibrating over 2,000 lines of convoluted, virtually impenetrable engine management information. A cold-air consumption, oil cooler, intercooler, and stainless-steel exhaust are also integrated. The suspension is a Dinan coilover setup, and every little thing is entirely adjustable: collars, finish backlinks, camber plates, ride height, and bump-quit clearance. Dinan supplies its very own rear toe hyperlinks, front sway bar, and bearings. 1-piece, 19-inch BBS wheels proudly bear Dinan center caps, wrapped as they are with Michelin Pilot Super Sports. There is a 4-12 months, 50,000-mile guarantee. The Dinan badge is free of charge and very carefully applied as it has on each and every Dinan-tuned car for the previous 23 many years. If you inquire nicely, Steve Dinan might provide you with the same checkered-flag graphics as our test automobile.

And but, the Dinan-tuned 1M isn’;t going to feel like a tuner automobile. It is quiet and effectively-insulated from the street. It doesn’;t deafen like so numerous Akrapovic-armed M3s at Targa Trophy its exhaust isn’;t going to bleat or fart continually. The turbos kick in at all around 3,000 rpm, and there is so much torque by way of the complete variety that you can leap into sixth gear at any time and chug around. The clutch is light and springy, and the shifter feel is normal BMW that is to say equally springy, unchanged from time eternal, and worthy of its decades of praise from guide-transmission lovers who have not driven a Mazda MX-5 Miata. Its amazingly company ride is the only evidence of tuner silliness we could locate. We have been informed that the dampers were set to medium stiffness.

But the trip forces you to readjust your priorities and reside like an ascetic, foregoing creature comforts for enlightenment. I have by no means driven a car far more agile than this. In which on most sporty vehicles you can ascertain a specific point of rotation, this car turns instantly with the accuracy and fervor of a homing missile. Move your hands an inch to the left or right and bang, the auto has already completed changing direction. Throttle responses are equally sharp. Dinan wisely chose to depart the 1M’;s stock Brembo braking program alone, most likely because it is smooth and reassuring, assured at panic stops and controllable at any speeds. Push it on a canyon road and the automobile just offers and gives and offers, asking the driver, “Come on. Is that it?”

So significantly power is inherently harmful. I’;m amazed that my time with the automobile did not consequence in a police standoff. What Dinan has produced right here is an definitely brilliant destroyer of tires and driver’;s licenses, and it really is up to the 740 fortunate 1M owners (and 220 Canadian folks, let us not neglect about them) who can pony up $ twelve,194 for the engine upgrades and $ 4,296 for the suspension to figure out their own levels of duty. Due to the fact it is not as significantly fun if the cops do that for you.
