R33 GT-R Update: TEIN Mono Flex Suspension with EDFC

What can I say about the Tein Mono Flexes and the Electronic Damping Force Controller (EDFC)? Since that was quite a mouthful, to sum them up in one simple word - just plain AWESOME!

They've totally changed the whole feel of the car, and having the EDFC controller at your finger tips is just such a joy. They have once again made me fall in love with the R33 and I can't help but look forward to the next time that I'm behind the steering wheel. The feeling that you get is actually is quite similar to Audi's Drive Select in terms of damping and traction (Comfort / Sport / Dynamic). This very positive experience came as a pleasant surprise, as prior to purchasing the TEINs, I've never sat in a car that was equipped with TEIN Mono Flex and EDFC.

PIMPIN, a fellow Skyliner who owns a BNR34, is an ardent supporter of these two TEIN products... so much so that he has installed the Mono Flex / EDFC combo in all of his previous rides (including the R34 GT-R)! Even with that sort of endorsement by a close friend, I was still a bit sceptical. I was worried that the TEINs would be stiffer than my old HKS Hiper-Ds - even at it's softest EDFC setting. As for the HKS suspension, I've never been happy with them because the Hiper-Ds are VERY bouncy on less than perfect roads (poor damping) and they don't inspire confidence when taking sharp bends or corners (very floaty to say the least).

Now my main concern was that at first glance, the spring rate on the MonoFlexes are EXTREMELY high. So one would immediatly assume that the ride would be harsher (case in point, the side by side pic found above). Before I go any further, lets have TEIN explain a little bit more about their Mono Flex and EDFC:

The MONO FLEX coilover kit has been developed for entry-level competition motorsports and advanced street driving. Features include 16-way damping force adjustability (combined compression and rebound), a mono-tube internal design, pillowball upper mounts, and EDFC compatibility. There are independent adjustments for ride-height and spring pre-load settings for increased suspension tuning. The new Mono Flex also includes TEIN's latest technological innovation, Micro Speed Valving (MSV) system, which allows the driver to feel a greater difference in damping force adjustments. Designed and developed for consumers seeking aggressive handling on the street and at the track.

The EDFC (Electronic Damping Force Controller) makes it possible for the driver to control the damping force at the touch of a button while in the driver's seat. This is accomplished by controlling stepping motors installed on each shock absorber. Because the damping force can be controlled with such ease, the driver can adjust the suspension to suit all road/track conditions. Thus allowing the driver to fully enjoy the driving experience.

By inputing your preferences into the controller, the new setting will be transmitted instantaneously to those little small boxes that you see on top of all four of the TEIN suspension mounts.

I found out very quickly that setting the EDFC to 0 Front, and 0 Rear resulted in you feeling EVERYTHING on the road surface. Sort of like dragging yourself naked across the street. This prompted me to increase the settings to 12/14. Immediately, the harshness subsided. TEIN did an unbelievable job with their spring and damper design, which resulted in the production of the MonoFlex. With the settings at their softest (16/16) I was able to experience a near stock like ride quality at low speeds. Of course, the same is not true when I bumped the EDFC up to 0/0 once again. You felt everything, and it hurt. Definitely not the sort of setting that one would want when cruising down inner city roads. On smooth highway asphalt though, the 0 / 0 literally blew me away. I could easily carve corners at significantly higher speeds than I ever did with the HKS Hiper-Ds. The TEINS seem to make the car that bit more predictable and gave me the confidence to push the car slightly closer to the limits. They also help in the traction department especially when launching the GT-R, as the rear is squats easily due to the softer damper.  I reckon 0 / 0 would be superb on a track like Sepang, where you really get to test the TEINs to the maximum of their ability.

HIGHLY recommended.

Rainbow tyre well thanks to the yellow of Whiteline and Goodridge, blue of Cusco and green of TEIN. Soon to be joined the matt silver of Nismo (strengthened lower rear A-Arm).

Technical Information

The Q5 shares the same platform as the B8 A4 and is powered by a 155kw two-litre turbo engine (211 hps / 350 Nm of torque). The car does 0-100 100 km/h in 7.2 seconds. This engine is not an updated version of Volkswagen’s popular MKV Golf GTI 2.0 TFSI (147kw). It is actually a new power plant of the "EA888" generation of engines which powered the GTI Edition 30, a special model released to commemorate the 30th anniversary of the GTI. Also, unlike the front wheel drive Golf, the Q7's little brother comes with Audi's signature quattro permanent four wheel drive system. Another interesting titbit is that the Q5’s front suspension is borrowed from the A4 and its rear from the A6/A8 line. Lastly, the Q5's engine is mated to Audi's 7-speed S-Tronic twin clutch transmission.

Exterior

Ever since I saw the car in the flesh at this year’s Melbourne International Motor Show, I always thought that the Q5 was a handsome car. This perception was only reinforced when I walked up to my test unit which was parked outside Euromobil's Audi hanger. From the car's futuristic LED headlight cluster, to the rakish design of its tail lights - the car just oozes masculinity. I did notice though that when looking at the Q5 side on, it looked a bit 'tubby' but this was probably due to the solid white color (Ibis White). I'm sure the S-Line version with 19 inch rims and a darker metallic paint option will sort this problem out!

Bottomline, I personally think that Audi's baby SUV looks much better than BMW's X3 (both the current & future model) and Volkwagen's Tiguan.

Interior

The interior was bedecked with supple black leather and I was able to find a comfortable driving position, thanks to the Q5's electronic seats (complete with lumbar support). The red dials on the speedometer, a Audi trademark, is clear and quite pleasing to look at. Like most Volkswagen AG cars, the driver's information screen is sited between the rev-counter and speedometer. It always shows the current selected gear and the driver is able to access information about the car by utilizing the steering wheel buttons.

The Audi sales rep gave a brief demonstration of the MMI system by slotting a SD Card into the centre dash and played some music tracks at the touch of a button. The Malaysian model is equipped with Audi’s Symphony radio and sound quality was pretty darn good. The Euromobil employee also connected his mobile phone via the Bluetooth prep system and it was all rather simple and easy to use.

My previous ride was a Volkswagen and there is a marked difference in terms of cabin quality. The Audi felt more upmarket. This should be the case anyway since even though VW and Audi are under the same corporate umbrella, they target different segments of the driving public. Overall the cabin was just about right - airy and well built. The car's luggage capacity is 540 litres and spacious enough for the needs of a young family. The rear seats are comfortable as well, according to a friend of mine who came along for the ride. As for those people who love being in a position of control or authority - not to worry, the Q5's SUV height gives you a throne from which you can lord over other road users!

On The Road

Before leaving Euromobil, I had already begun to fiddle with Audi's Drive Select system. While making my way out of the tight small lanes of Kawasan Perindustrian Temasya, the Q5 in Comfort mode was supple and the light steering wheel setting, made for easy manoeuvring. There was little body roll, even during sharp turns. Pot holes and road irregularities were soaked up by the cosseting ride. Upon reaching Jalan Lapangan Terbang Subang Jaya, I switched to Auto mode and you could already feel a difference in terms of power delivery and ride - pick up had improved and the car felt more planted. The steering wheel began to feel 'meatier' too.

As I passed Saujana Golf & Country Club, I swapped to Dynamic and after making sure that there weren't any other road users near me, began to move the car from side to side while at cruising speed and the Q5 felt unbelievably solid. The steering wheel felt so direct and meaty yet never too heavy. You just had to point at where you wanted the car to go and it went! The ride was slightly more on the firm side, so some people might find it a bit too harsh for daily driving (but that’s what Comfort mode is for isn't it?). I reckon that Dynamic is just perfect for a blast down the highway or for some spirited driving on nice stretch of winding road. Prior to returning the car to Euromobil, I couldn't resist doing a standstill launch to see if the 7.2 seconds figure was accurate. Needless to say, thanks to the engine, the quattro four wheel drive system and the lovely gearbox, the car is capable of doing just that (not to mention making me smile with the sudden rush of unadulterated speed!).

Conclusion

Try to imagine the Q5 as a large hot hatch and you would probably have a good idea of what the car is all about. It definitely isn't an A4 on stilts. Despite weighing in at a hefty 1730kg (unladen), the car is fast, handles well (for a SUV - feels more like a premium sports sedan) and isn't so large as to make the task of driving it around town a chore (try parking a Q7 on a weekend and you'll see what I mean). Some people might argue that buyers are better off purchasing Volkswagen's Tiguan rather than spending RM50,000 more on the Q5. Having driven the Tiguan (which is based on the MKV Golf chassis - meaning its smaller than the Q5), I would say that if you could afford to spend fifty grand more, you might as well get the Audi. By doing so, you get the S-Tronic / DSG gearbox (Tiguan has a regular 6 speed transmission), a much more powerful engine (the VW's powerplant puts out 147kw and does 0-100 in 8.5 seconds) and the Q5 will have a longer shelf life since its European launch was in November 2008 (the Tiguan was launched in Europe in November 2007).
