R33 GT-R Update: R34 GT-R Steering Wheel Swap

Not many people know this but R34 GT-R steering wheels are plug & play when it comes to Series II / late model R33 GT-Rs. Airbang and all mind you, with no error lights showing.

Now theres nothing wrong with the stock R33 GT-R quad steering wheel. Its just that it doesn't have much character going for it. I mean, it only has an embossed 'Nissan' on the horn button, along with the corresponding moon corporate logo and outer red leather stiching. It was also present in the Silvia S14 and other Nissan models like the Skyline GTST (ENR33 / ER33). No offence to the owners of those cars but I wanted a steering wheel that had a tad bit more GT-R exclusivity. Nissan must have really liked the design by the way, because it was still in use in their first generation X-Trail! Ahh, you've served me well old girl...

I've always been a fan of the R34 GT-R steering wheel, mainly because of the tri-star sculpted design and the prominent 'GT-R' horn logo. It's also smaller by an inch or so in terms of diameter. No prizes for guessing where I managed to source a unit (thanks to my good buddy Eu-Jin at JDM Auto Link). Supposedly, these are quite rare and difficult to source.

It was a pretty straight forward affair in removing the stock steering wheel. I knew that the airbags in the two steering wheels were of the same model, but there was no harm in checking. To do this, the side latches were opened up and the airbag housing unscrewed. Fortunately, the sockets all matched up, so we were good to go. Do note that this modification is only possible in Series II / late model R33 GT-R's, that feature driver and passenger side airbags. If you have an older BCNR33, then you're unfortunately out of luck. This is confirmed for Series I R33 GT-Rs. Oh and did you know that airbags have a shelf life? The one in my stock R33 GT-R steering wheel has clearly gone pass it's expiry date (circa 1997!), while I'm hoping the R34 GT-R's airbag is still good for a couple more years. Food for thought, gentle people.

Now all that was left to do was to line up the R34 GT-R steering wheel and bolt it in. I have to say that due to the tri-star design, the steering wheel feels much smaller and more chuckable. I just love it because it's a straight fit (no adaptation needed), looks like it belongs there in the first place, is much smaller than the unit that it replaces and really spruces up my R33's interior. Aki, you should really do this mod, mate ;).

New rims and tyres for the mystery car

It came with stock 17" factory rims and that setup didn't do the car justice. Hence, I immediately set about rectifying this problem. And so, a few weekends back, I made my way to Hup Shun in Sunway PJS 11/7. According to local motoring afficianados, this particular shop sells genuine rims and tyres at lower prices when compared to other places in the Klang Valley.

While browsing through the selection of wheels that were on display, a Hup Shun employee asked me what was my poison. I explained that I was looking for 18" x 9.5" +12 rims. He replied that strangely enough, a R34 GTR had come in earlier in the week to get its Volks Racing RE30s replaced with Volks Racing TE37s (the former came in bronze). He also mentioned that the rims were up for sale and were barely used.

Some Hup Shun technical staff then carried the four rims in and I could see that he was speaking the truth - they looked almost brand new. For those who are not aware, RE30s are one of the lightest rims available on the market. The 18s for example, weigh only 8.10 kg. The TE37s on the other hand weigh in at 8.45 kg. So I'm not sure if the R34 owner was actually "upgrading" but rather the whole exercise was more for looks, as the TE37s are a better match for the sharp edges of the BNR34.

RE30

Needless to say I was pretty much sold the moment I lifted up one of these babies. They were so light. After checking all four for any signs of damage and finding none, I asked the Hop Shun employee what tyres they had in stock that could fit the RE30s. He said that they recently brought in 6 units of Bridgestone Potenza S001s. Now I knew that the S001s came on the market in early 2010 and were actually factory fitments for the Aston Martin Rapide and Ferrari 458 Italia. It was also going to be used in the soon to be released Lexus LFA as the car's factory fitted tyres.

Here is the product description by tiretrack.com on the major features of the S001:

The Potenza S001 is Bridgestone's Max Performance Summer tire developed as Original Equipment for premium high-performance sports cars, coupes and sedans. The Potenza S001 is designed to combine low rolling resistance efficiency with maximum sports performance in dry and wet conditions. However, like all summer tires, they are not intended to be driven in near freezing temperatures, through snow or on ice.

The Potenza S001 features an asymmetric design combining a large outboard shoulder, interlocking tread blocks and a central circumferential rib to enhance dry road steering response, high-speed stability and cornering precision. Notches in the shoulders expel water to the sides while high-angle lateral grooves in the intermediate ribs pump water into the wide circumferential grooves to help resist hydroplaning.

The tire's internal structure features a lightweight belt package consisting of twin steel belts supported by a spirally wrapped aramid/nylon cord reinforcement that reduces rolling resistance, enhances ride quality and ensures high-speed durability. Active rubber inserts in the sidewalls near the bead areas tune vertical sidewall stiffness to blend cornering grip with ride comfort, as well as increase longitudinal stiffness to generate straight-line braking forces.

To cut the story short, I purchased both the RE30s and the S001s (265/35/18) that very day and they are now on the mystery car. Very, very happy indeed with the results despite having to cough up some dough.

I'm pretty sure people will be able to figure out what the mystery car is by this point in time ;). Till the next mod entry, readers...
