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 would possibly 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 whole lot of issues for sure sorts 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 laws for many years.
However regardless, on the finish of the day, BMW managed to create an important chassis packaged in a number of completely different and compelling trim ranges. I’ve pushed my dad’s F83, which I really helpful he buy as soon as he turned rigid in his standards to purchase a sporty automobile with a retractable hardtop, and I’ve additionally pushed an M4 GTS from the identical technology.
After each of those, I drove this automobile, the LAPTIMZ Motorsports-built F82 M4. However to know the evolution of this particular chassis, it’s initially extra helpful to debate the variations that BMW themselves launched straight 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 automobile is snug, compliant, and usable. It makes the best noises, but it surely’s not loud and doesn’t actually put on you out on an extended journey, even in case you’re making it work exhausting on a backroad for a portion of your journey.
The GTS was a lot harsher, and you would 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) non-compulsory carbon fiber wheels multiply the coolness issue on the GTS, particularly as these options have been designed, engineered, and put in by BMW.
Finally, the bottom coupe, F83 convertible, and limited-production GTS are all nice choices in their very own proper. However all have been finally hampered by being designed as mass-produced street vehicles, although it’s value stating that the GTS was restricted to simply 800 models, 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. In fact, BMW ended up promoting over 3 times that quantity of E30 M3s anyway, so while you’re speaking about manufacturing numbers within the lots of, these figures as a substitute 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 as we speak. To get the identical kind of ‘I’m driving a race automobile’ feeling that you’d obtain from a real homologation automobile, you need to look to the aftermarket as we speak. And that’s why I’m so into this explicit M4.
In fact, you don’t get that collectible factory-delivered cachet of the GTS. However so many trendy particular version vehicles as we speak are merely workout routines in the right way 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 part was accomplished by LAPTIMZ Motorsports, and as you’ll be able to see it already was nicely on its approach to being a race automobile on the road. The unique Mineral Grey Metallic labored nicely with the darkish Apex wheels, carbon fiber hood, and aero elements, however what I beloved most about the automobile was the super-clean execution of all the modifications.
The extra time I’ve spent round modified vehicles, the extra clear it has develop into to me that it’s exhausting to switch a contemporary efficiency automobile 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 might have opted for non-halo seats and fewer aero for extra of a avenue automobile bias, however the proprietor of this M4 is an avid and skilled racer who was trying to take this automobile to a better monitor specification.
Truly, LAPTIMZ Motorsports was working with the unique proprietor of this M4, who wasn’t prepared to surrender all the streetability that the F82 supplied, so this good steadiness was struck the place the automobile nonetheless had a full trunk, air-con, and almost all the manufacturing facility facilities in addition to these soft inventory seats.
Below the hood, solely a Dinan carbon fiber consumption was added alongside a Dinan exhaust, and extra energy was discovered through a tune. However finally, this wasn’t sufficient for the proprietor, who needed 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 automobile for NASA and SCCA competitors.
Evolution
A CSF Race intercooler was added by Vt Motorworks in Pleasanton, California together with a slew of supporting components — 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 classes.
On this automobile, 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 permit 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 best containers have been checked underneath the hood.
Externally, the automobile was wrapped, and color-coordinated Forgeline wheels have been fitted over the present 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 traces and aero on this case.
Inside, issues have gotten a entire lot extra critical, however though the cockpit is solely function-first, kind hasn’t been sacrificed within the slightest. Fabrication of the cage and the stainless work refinishing the naked inside was accomplished regionally by Tony Colicchio of TC Design. I really like how good this automobile seems stripped down, and you would go a bit additional on this regard, too.
LAPTIMZ Motorsports has put collectively a very spectacular package deal over the course of some years, and I really like that their shopper — once more, the unique proprietor — has used this automobile on every thing 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 automobile go to the best bidder on Deliver a Trailer, which is why I used to be reacquainted with it once more lately.
Though this construct is actually arrange as a race automobile 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 after I learn to really drive, and pulling as much as a vehicles and occasional in an incognito-mode race automobile. Oh, and I’d drive it to Laguna Seca, rip across the monitor and cruise again house once more each probability I obtained.
The F8X platform is actually rising on me.
