I've ordered the Street Performance with 10/4 for my R33 GTS-T, also keen to see how they ride, I went around in circles for ages looking at all the options, it does your head in, everyone's opinion is different. But I'm confident I've made the right choice in the end.

Back in my day, they only had Blue, Red, Gold [emoji14]
Same, but I was too poor for reds so I went blues. I'm not complaining though, although slightly harsh for the street, it has been perfect on the track (14kg front and 9kg rear)

I want to say this is because MCA have always used 'different' sping rates and make the difference up with valving.

Or something. Their numbers have always been signifigantly higher but it doesn't translate to 'more hardness/firmness' as such as if you ran around running 14/11 BC's or Bilsteins or Tein's or Shockworks or etc.

I agree Kinkstaah, high spring rates don't mean everything and it does depend on valving, however having one of the first sets of blues that came off the line I can confirm they are valved somewhat agressive (have heard from someone who had purples say the valving of my blues was a lot harsher). I don't know if this has changed since the blues were first released but they are definitely not valved to be comfortable haha.

As mentioned even in the last year their product range has about doubled and their naming has changed to boot. Makes sense that they're continually refining the product, I guess as they can now say "WTAC Winnars" you'd want to make sure your product is front line and catering to as many needs as you can :P

Their pricing has also had a bump and if you want custom none off the shelf spring rates that's another $50 on top.

But yes high spring rates mean nothing, I was probably one of the first to try out their X-Series range with success and high spring rates back 2-3 years ago, funny enough they didn't even have boxes to fit R33 rear coilovers in so mine came in a king springs box lol 

Dirty plug, I can get MCA stuff too now

Thread revival.  I don't suppose anyone has a review of the new MCA range now they've had them fitted?  I'm looking at MCA performance for R33 but the 10/4kg rates are making me think otherwise.  These used to be 10/7 when they were reviewed here last.  The front to rear difference has me concerned.  4kg is about the same as whiteline springs while the front is more than double.  I just can't get my head around how these won't understeer like crazy. 

Shockworks have a 8/6 as standard package but no stock for 6 weeks. 

 

 

MCA usually spec their shocks with standard sway bars.

Plus I think "ride" and performance are more to do with valving than spring rate alone.

I sold the GTR but I still have my track Silvia and i took their advice on what to change with the setup, not even using their coil overs and the car is better so I have some faith in what they say. 

They did also provide the suspension for the WTAC winning S13...

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
