Nitron NTR R3 Coilover Systems, BMW E85/E86/Z4 M

NTR R3: The Pinnacle of Nitrons most Dynamic Race Suspension Systems.

Most people are aware that suspension is essential for high performance cars, and many have a vague idea of how most of it works but very few understand the finer details and understand how to get the best out of their car through correct setup. Unless you’re a racing driver with many hours experience, suspension can seem like a bit of a dark art. Multiway systems more so; with seemingly endless configurations and permutations 2and 3 way systems seem out of reach for all but the most hardcore.
After several years of working to improve the handling of many race cars and bikes, designing and producing every conceivable suspension component, Nitron Racing Systems was officially established in 1998 with the primary objective of producing the very finest racing shocks and backing them with unrivaled performance for the racer. Since then, Nitron’s worldwide success has spanned over a decade of prestigious race wins and lap records on both two and four wheels using the revered NTR series of shock absorbers.

Today, with direct motorsport involvement and a committed development program, every Nitron customer experiences cutting edge performance and design, proven on the world’s most demanding circuit and the latest evolution of technology in the NTR line. Here, Nitron offers its most prestigious and capable system ever conceived: The R3.
Always focusing on delivering serious performance and not compromising on design and build quality, both internally and externally- Nitron is the solution the most serious BMW racer needs to best the competition!
 

NTR R3: Complete Coilover Package for your BMW:
We like different cars. We modify our cars to be individual. We each have our own driving style – and at the highest professional levels, cars are tuned with feedback from the driver and to have the edge over the competition by having adjustments that can "add" traction over less than perfect surfaces and on tracks that are challenging.

You are going to need the ability to make precise adjustments to have the edge. The R3 damper as Nitron's top of the line damper make no concessions, its for the pro or aspiring pro racer that looks for independent adjustment of bump and rebound, and even go one step further by offering both high and low speed bump control.
Low speed bump relates to roll, dive, squat and translates into the ‘feel’ that the driver gets when putting the car though its paces on track. If a car is struggling to put its power down and gain traction, softening the low speed bump will make the suspension more compliant, allowing the car to then deploy power more effectively while still offering resistant to roll. High speed bump control is about track use with a varying surface; thus allowing you to tune the suspension so that the car travels over curbs and rumble strips with reduced disruption to the chassis, allowing you to "widen" the track and follow an ideal racing line. If you face races in the rain or over a loose surface, the R3 is your ally in making the car feel planted yet sharp on these often treacherous and challenging scenarios.
More user friendly adjustment ultimately means the most dynamic performance for a given situation, giving these three-way adjustable dampers the most tunable performance to the drivers exacting preference.

That leads up to the type of adjustment and the range of the Nitron damper: Beware of just how much adjustment some after market damper kits offer – many kits in this price range state anything up to 40 clicks of adjustment! However they are usually not linear and often only have 5-10 clicks that actually make difference to the damping curve. Nitron shocks arrive (preset, may we add) with around 26 totally linear clicks. For most customers this means a simple initial setup process to find their individual ‘sweet spot’ and a ‘less 2 clicks’ for a wet set setup.

Remote reservoirs offer two very distinct advantages for serious performance automobiles: Lower operating temps and consistency over a long period of time. Consistency wins races and Nitrons generous amounts of oil and gas allow fade-free performance over any surface. Think of this is the same way a big brake kit offers extended performance by its additional capabilities to turn the cars velocity into brake heat, a very similar situation to the oil in the damper.
Also, remote reservoirs allow the lower valve to be located externally of the dampers stroke, that would normally be at the bottom most portion of a shock. This is allowing for tremendous amounts of travel and accurate valuing- imagine the chassis attitude during braking over bumps, rumble strips, track off or elevation change scenarios: having additional bump (compression) travel is a very handy thing indeed!

While a race suspensions job is to help keep the car in its most ideal state, with as much contact patch maintained to the road surface, the "race" moniker often fools the customer: Race suspension must allow for irregularities to be absorbed and their effect on the chassis quelled as quickly as possible. Perhaps then, the most impressive thing about the R3 Nitron shocks is that they are so capable, that even with 'race valving' and race spring rates over 1100lbs, our E92 is daily driven though the broken roads of urban Philadelphia with an unimaginable level of comfort, and could be used without issue on a street car (rear shock mount reinforcement is recommended in some instances).
Over the challenging surfaces and high speeds of the Nordschleife, which even professionals fear, the R3s job is to keep total composure of the chassis at life threatening speeds. Not only is it suited to this daunting task, but the R3 coilover system is the VLN record holder on the 'Ring with an N/A E92 M3.

We are proud to say that Nitron is equipped on many record holding BMWs and other vehicles around the world and has an unrivaled success rate on the E36 and E46 chassis, with just one example being a 7 time (in a row!) Overall 1st Place and overall championship win in the CSL Cup!

Nitron R3 on the VAC world record holding Supercharged E92 M3: Wow. The R3 on our car is an absolute revelation. The funny thing is how much the myth of "track suspension is harsh" has been proliferated all over the internet. Lets first say that we daily drive this M3 all over from Philadelphia, to New Jersey and New York. There are few and far between a nice road in the tri-state area and the R3 kit was literaly installed on our car with the race valving and springs used for touring car racing. The Nitron R3 on our car were sent to us as a test set, with the confidence of Nitron being the typical reserve and polite British  "Give these a go, there're quite good". Legendary understatement: if you want the best of the best for an unrivaled price there is no other choice to look at other than the R3. Accomplishments on R3 kit: -Comfortably driven on 1200lbs race spring rates! -Mid 10-second drag passes (current world record) -1.30:00 lap times around NJMP Thunderbolt, first time out with no setup changes (that would be pole-position qualifying in a Grand Am car) We feel that the R3 kit is superb for any BMW you wish to have as competitive as possible on the track, but also- if you attend about 1 driving even/ DE/ Auto X a month, you can really feel the performance and tuning benefit of R3 on a Weekend/dual use or hobby level car!
