The F82 M4 was BMW’s probability to, as soon as once more, construct ‘The Final Driving Machine.’ They succeeded in some senses, although in others they missed the mark.
Regardless of the varied shortcomings area of interest teams may wish to level out, on the finish of the day, BMW was profitable in its foremost objective: to promote vehicles. This pesky objective creates a variety of issues for sure kinds of fanatics, resembling having snug, usable suspension, in addition to a great deal of leather-based, semi-luxurious tech options, and security gadgets that add weight. Plus, exterior styling has been getting additional and additional stymied by rules for many years.
However regardless, on the finish of the day, BMW managed to create a fantastic chassis packaged in just a few totally different and compelling trim ranges. I’ve pushed my dad’s F83, which I really useful he buy as soon as he grew to become rigid in his standards to purchase a sporty automotive with a retractable hardtop, and I’ve additionally pushed an M4 GTS from the identical technology.
After each of those, I drove this automotive, the LAPTIMZ Motorsports-built F82 M4. However to grasp the evolution of this particular chassis, it’s initially extra helpful to debate the variations that BMW themselves launched instantly from the manufacturing facility.
Unshockingly, the expertise between the inventory convertible model and the extremely factory-spec GTS version was night time and day. My dad’s automotive is snug, compliant, and usable. It makes the appropriate noises, but it surely’s not loud and doesn’t actually put on you out on an extended journey, even if you happen to’re making it work exhausting on a backroad for a portion of your journey.
The GTS was a lot harsher, and you could possibly instantly discover simply how a lot stiffer the chassis was with the spectacular manufacturing facility roll cage versus my father’s roof-less model. And the insane titanium exhaust that was solely fitted to the GTS all the time begged so that you can step on the throttle. The carbon fiber roof, (problematic) water/injection system, (problematic) billet uprights, and (problematic) optionally available carbon fiber wheels multiply the coolness issue on the GTS, particularly as these options have been designed, engineered, and put in by BMW.
In the end, the bottom coupe, F83 convertible, and limited-production GTS are all nice choices in their very own proper. However all have been in the end hampered by being designed as mass-produced highway vehicles, although it’s value declaring that the GTS was restricted to only 800 items, which is a far cry lower than the 5,000 E30 M3s that BMW was required to construct for homologation functions again within the day. After all, BMW ended up promoting over 3 times that quantity of E30 M3s anyway, so if you’re speaking about manufacturing numbers within the tons of, these figures as an alternative invoke ideas of the 501 examples of the E30 M3 Sport Evolution II that BMW constructed.
Whereas the GTS did really feel — and sound — particular, it didn’t really feel almost as particular to drive as an E30 Evolution feels to take a look at, and it definitely didn’t have any of the appeal that even an ordinary E30 M3 has at present. To get the identical form of ‘I’m driving a race automotive’ feeling that you’d obtain from a real homologation automotive, you need to look to the aftermarket at present. And that’s why I’m so into this specific M4.
After all, you don’t get that collectible factory-delivered cachet of the GTS. However so many fashionable particular version vehicles at present are merely workouts in find out how to market and money out on the idea of exclusivity that, experientially talking, does that facet even matter to an fanatic who solely cares about driving?
Aftermarket
I shot this M4 shortly after its first construct section was accomplished by LAPTIMZ Motorsports, and as you may see it already was properly on its method to being a race automotive on the road. The unique Mineral Grey Metallic labored properly with the darkish Apex wheels, carbon fiber hood, and aero parts, however what I cherished most about the automotive was the super-clean execution of all the modifications.
The extra time I’ve spent round modified vehicles, the extra clear it has turn out to be to me that it’s exhausting to change a contemporary efficiency automotive and make it objectively higher. Similar to the unique producer, you have to select and select what you’re snug sacrificing.
If it was me, I’d have opted for non-halo seats and fewer aero for extra of a road automotive bias, however the proprietor of this M4 is an avid and skilled racer who was trying to take this automotive to a better monitor specification.
Really, LAPTIMZ Motorsports was working with the unique proprietor of this M4, who wasn’t prepared to surrender all the streetability that the F82 provided, so this good steadiness was struck the place the automotive nonetheless had a full trunk, air-con, and almost all the manufacturing facility facilities moreover these soft inventory seats.
Beneath the hood, solely a Dinan carbon fiber consumption was added alongside a Dinan exhaust, and extra energy was discovered through a tune. However ultimately, this wasn’t sufficient for the proprietor, who wished to go full tilt in his F82 coupe, which he bought model new. It was time to start out constructing the M4 right into a race automotive for NASA and SCCA competitors.
Evolution
A CSF Race intercooler was added together with a slew of supporting elements — from the cost pipes right down to the gas injector O-rings — to crank the facility up. Whereas many builders efficiently push tons of energy via CSF’s larger-than-stock cost cooler, this isn’t actually what it was engineered for within the first place. As an alternative, CSF’s cost cooler helps preserve the consumption air temperatures over prolonged monitor periods.
On this automotive, CSF’s cost cooler has been paired with their warmth exchanger in addition to an Energetic Autowerke equal-length mid-pipe and Dinan rear exhaust part, which simply enable for constant energy supply within the excessive 500whp vary. Consistency on all fronts was LAPTIMZ Motorsports’ objective for his or her shopper, so all the appropriate packing containers have been checked below the hood.
Externally, the automotive was wrapped, and color-coordinated Forgeline wheels have been fitted over the prevailing AP Racing J-hook-type rotor setup. The JRZ RS Professional 3 triple-adjustable coilovers with distant reservoirs have been already put in and simply wanted additional tuning to deal with the newfound energy.
A carbon fiber roof was fitted within the quest so as to add lightness, and whereas I’m not a lot a race livery kinda man, I’ve to say the M shade scheme and design actually enhances the physique strains and aero on this case.
Inside, issues have gotten a entire lot extra critical, however though the cockpit is totally function-first, kind hasn’t been sacrificed within the slightest. I like how good this automotive appears to be like stripped down, and you could possibly go a bit additional on this regard, too.
LAPTIMZ Motorsports has put collectively a extremely spectacular bundle over the course of some years, and I like that their shopper — once more, the unique proprietor — has used this automotive on every part from the freeway to the backroads to the racetrack for simply over 30,000 joyous miles.
However plans change over time, and the proprietor has determined to let this automotive go to the best bidder on Carry a Trailer, which is why I used to be reacquainted with it once more not too long ago.
Though this construct is really arrange as a race automotive at this level, it’s nonetheless technically streel authorized. So, if I used to be the winner, you’d discover me ripping off the wrap in my storage, saving the aero for a time once I discover ways to really drive, and pulling as much as a vehicles and occasional in an incognito-mode race automotive. Oh, and I’d drive it to Laguna Seca, rip across the monitor and cruise again house once more each probability I acquired.
The F8X platform is actually rising on me.
