R33 GTR upgrade from Nismo S-Tune

Recommended Posts

Hi Guys.

I've got Nismo S-Tunes in my R33 GTR.  I like the ride comfort and handling but at times you can still feel the car could do with something better.

I'm hoping to retain good comfort that the S-Tunes give but get better handling.  Has anyone here on a R33 GTR personally switched from S-Tunes to something else
and can give feedback?

I have read reports from a guy who went from S-Tunes to Ohlins and loved the difference in both handling with still soaking up the bumps well.
Having heard that feedback they will have to be the go, unless there is something locally produced in Australia that can be just as good if not better

Other option is MCA Reds which always appear to get recommended.    Oddly, Nismo and Ohlins have spring rates almost even, while MCA have the front almost double of the rear.

Hell even if the entry level MCA Comfort-Pro's are going to be better than dated Nismo design, I could start with them.

The car also does have 700hp, currently grips perfectly with no wheelspin, I was thinking to go the Ohlins as they aren't too heavy spring rates to help give some squat under power

Any advice appreciated keen to hear your experiences

Cheers.

Going off spring rates alone to gauge how harsh/firm they are doesn’t tell you much at all. You have valving and fluid used also to consider.

The springs in my current setup are 15 mm front/9 mm rear and are much better at soaking up a bad road than a set of “softer BC’s” (which feel like you have railway sleepers as suspension) and even Nismo S tunes.

You get what you pay for here and a $1099 set isn’t worth the box they come in. Might be 36,000 way adjustable but it’s hard, hard, hard, harder and hardest.

Bilstien PSS9’s and the Ohlin DFV’s are probably a good place to start or as you have already said, the guys at MCA. 
 

FWIW, I’ve had stock, Nismo S tunes, Nismo R tunes and the current setup which is Modified PSS9’s.

Do you have standard sway bars? If you do, and you're currently happy with the Nismo's, upgrade the sway bars first before looking at different shocks. They'll make the car more planted, especially during spirited driving, and if you get adjustable ones, you can tune the cars handling characteristics. How's the rest of the steering/suspension set-up/condition? Tyres etc. Must be okay if it hooks up with high h/p?

Whilst this is all true, it will conflict with MCA's approach, should you go down the path of getting coilovers from them. They are very much more in the "control roll with spring rate" camp rather than "control roll with bars" camp.

I can see the benefits of both approaches. Loss of independence side-to-side from using big bars is a negative. Hasn't stopped me from putting big adjustables on though. But then, mt spring rates are only in the 5kg/mm range.

Yeah, that's what I was trying to hint towards. If the OP is currently happy with his Nismo's, upgraded sway bars might be just the thing he is looking for. Put it this way, it is cheaper and easier to upgrade the sway bars first, than go all out with some new shocks.

    • Does this count as a time trial as well? I got all gold in the master super licence (1 lap time trial) and received a McLaren MP4/4 for my trouble.  If anyone else has done this, did you ride the wall right around the first long right hander at Lake Louise snow track to get gold? I couldn't do it any other way... best I could do without riding the was was within 2 tenths of the gold time.
    • I definitely get the low power, sporty car to drive to smash gears but not be doing eleventy million miles an hour! It makes all the normal drives fun!   Rev match tune sounds like the funs! I didn't know the NC had a DBW throttle!   As for me, still have the Skyline, it still has the Barra in it. It's been pushed to the side of the workshop at the moment. Pretty much waiting on me finishing the wiring, and dropping new fuel lines in. Got myself an ACDC Tig end of last year so been teaching myself TIG welding to build a few things for the Skyline. The missus wrote off her GTB liberty at the end of last year, and got it back on salvage rights stupid cheap. It's also still registered, so will mean easier for me to take to the track already done most of the panel damage, just playing "clear the workshop" to make space to pull the motor and box out, fix some oil leaks, replace the clutch, and replace a few minor broken things.  Also got a Lathe at the start of the year, which is adding to the annoyance of no space, which is another reason I'm trying to build things to get more space, to get the Lathe back in a final home for it. It's a BIG lathe, can turn a 355mm diameter, and 1metre between centres... Got it at a steal! So between it and the TIG and old MIG welder, I'll be fabbing some fun little shit up But we've had a lot of shit stuff happening at home, so it's slow going getting things done. But one step at a time!
    • I love Catalunya.  Got a 1:54.632. The AMG is a hoot.
    • I hadn't got that far, my main worry was the connection to the actual calipers themselves. I'm just using new (ish) stock brake lines in the stock setup. I've just had a stud welded to the knuckle that is a little lower than the original stud (so my knuckles have two studs each side) to not have it be stretched so far in previous BBK setups, so the "block" (in the second picture) mounts a little lower for me and I hope I don't need to change anything. I may have even changed the connection to the calipers in the past and have since forgotten I did that. I may not have. Guess how I'm gonna find out. Source: hopium
    • It's more so I'm using the 1x piece line from HEL that goes from the body to the caliper. There's no middle block/mount like the HFM ones or the GKtech ones. There are certain angles/suspension compression where the line actually slightly contacts the ARB. Below of how mine sit (not my photo): How I want it:
