I hate you guys!!!......

[Problem Child]

When I bought my NSX I said "No, I am keeping it in standard trim" Now here I am with a list as long as my arm of mods I have done and now plan to do. It started with changing the gear knob. No harm in that (or so I thought), then it was the antenna. Changed it for a small rubberised "bee sting" style, and lost my AM coverage as a result. Then came the Double Din hifi/ phone/ DAB/twatnav (which is fantastic! and got Talksport back too). Oh, dont forget the water pump, belts and cam belt etc etc

New wheels and a ZD exhaust are both on the list for later this year

I also have a spareparts bin second to none!

Its going for a paintwork detail next weekend and to do it properly he has to take off the rear spolier. And that got me thinking.....Whilst its off why not replace it with a carbon fibre NSX-R rear spoliler? I fancy the CF version as mine is a red on red NA2 and its just too red, so thought the CF would break the red up just a bit. Looked at the real thing @ £4800, then there is the Seibon or the Taitec versions (with rear light fitting). Which do you recommend? Thoughts please

Love you guys for the advice you all give but hate you for getting me started on the mods!!!

Hi, Geoff.

If you are installing the wing for the looks, then that’s fine.
If you are going for the aero reason, then think twice because the downforce is too much for the standard NSX chassis setup and you will loose steering info at high speed.
NSX-R wing was carefully designed using wind tunnel with NSX-R setup. This is the reason why Honda Access designed completely different rear wing for their Modulo NSX.

Please note that the panel/wing/etc alignment of any exterior parts (regardless of OEM or aftermarket) installed after leaving the Honda factory won’t be perfect.
This is because each NSX has been assembled with different thickness of shim and the aluminium panels were hand beaten or even carefully filed by the selected craftsmen that even a new OEM panel won’t be a perfect fit without these special treatments.

Taking the above points in consideration and from what I saw on many NSX in Japan and UK, I think one of the best quality/fitting is the one from Detlef, Procar Specials.

He has access to the real NSX-R parts so this is one of the reason why his product has good alignment.
For the rear wing, I think there were several options such as with/without the 3rd brake light, the coating/surface finish, etc but best to check with him as I think it’s not stocked regularly.
You can find all sorts of contact details for Detlef through his vendor page in ‘NSXCB Vendors’ forum.


Not sure whether 'Sudesh' has the rear wing in his product range or not but worth checking with him.
No doubt you have seen his ‘Refresh’ thread and that tells everything.

Hi Geoff

I did say to Senninha last year that you were on the slippery mod slope when you were salivating over his exhaust note!

Nice to see that have finally come around to the fact that red/black are faster than all red, not sure a CF spoiler counts as black though, lol.

As you know, I have front and rear aero package for reason explained by Kaz ... However, not sure you'll be fast enough to worry about it :D, so should be fine with rear only.

HI Geoff,

Is this the look you're after? R replica spoiler, should think about 02 rear valence and then a nice set of alloys.

For the spoiler \ rear valence go to www.scienceofspeed.com (http://www.scienceofspeed.com) if Procar out of budget ... choice of OEM replica spoiler of the Df version (same as mine) as I prefer the lines of this. As for the alloys, I can put you in touch with Chris on Prime who has either a 17/17 or 17/18 set if you're quick

and BTW, the car you refer to was Black \ Red, not plain slow red ;o)

regards, Paul

[britlude]

oh dear... it's a slippery slope.....

[TheSebringOne]

I wonder how many true OEMs are left out there, apart from the tyres?

[drmikey]

I was going to opt for a downforce one but even the FRP one was going to work out twice the price of the Seibon carbon one by the time it got to the UK

hi paul

did you get the rear valence kit from SOS?

is it a good fit?

instead of baiting geoff you now have me on the verge of being hooked :)

FWIW Kaz is right about the light feel on a stock aero front NSX, just my .2p.

DF-R rear spoiler as I prefer the way it aligns to the boot lid sides. My valence is OEM sourced from Dirk.

I suggested a multiple unit purchase as from the States you might as well bundle as filling a large box with several items is cost effective .... I might add to an order if one is made as I looked at a part recently that was $250 yet would cost $280 to ship on its own.

regards, Paul

[nobby]

Thanks Paul,

Re SOS I was looking at this link for the valence - http://www.scienceofspeed.com/products/exterior_performance_products/NSX/aero_underbody.asp

Would this be the correct kit ($850)?

i would be interested in seeing if any other members was interested and perhaps get a few shipped in one box; SOS shipping can be expensive so every little helps.

Interesting comments re NSX-R rear spoiler ... Still would like one though

[m666 edd]

Just an observation - The SoS supplied rear valance is only suitable for US/JDM models due to the number plate recess dimensions so would be fine for nobby's Japanese spec NSX but not for the majority of the UK spec NSXs here.

[Silver Surfer]

At this rate..by the end of this....Geoff will have the most modified NSX.. rather than the most OEM he initially indicated......;)

[nobby]

Jee whizz, I actually forgot about that issue!

need to drop SOS a line to find out a bit more about their kit.

[Senninha]

For info my valance is also JDM but works with the UKDM set up ... a small 'mod' by Dirk that I'd guess would work for the SoS (DF) valance

Andrew, a call into SoS should be able to clarify this for all.

[m666 edd]

Paul, Does the 'mod' add to the number plate recess area so it matches the upper bumper? Sounds like a good solution whatever it is!

Andrew, it wasn't intended to be a 'smack in the head' I thought I worded it well :)

We should start a thread dedicated to Mods, I bet it would get a lot of posts. People seem scared to start threads but not reply to threads.

[Senninha]

TBH I dont remember what Dirk did as he did this ahead of delivery to me. The upside is that yes, it works with the UKDM number plate set up ...

Lol ... U had it worded very well but smack in the head by myself re this :)

getting back on track, these are new and coming to market in May

http://www.ozracing.co.uk/car_wheels_var/OZ%20Racing/25182/I%20-%20TECH/FORMULA%20HLT/561089.aspx#

I don't know if they offer the right offsets for our cars, you will need to research this. The spoke design running to the edge of the rim makes them look larger, so. 17/18 combo would give you the stance of the earlier photo. Prices from £300 per wheel is good too.

Nice but I think I will stay with 16/17 combination, and try to get a twin 5 spoke wheel....these ones start at 17"

[nobby]

Geoff, if I was looking at replacement alloys I would definitely consider bigger wheels perhaps 17's all round or what Paul has stated. The NSX has a better stance with bigger wheels, but your choice at end of the day. Good luck with whatever you decide

[Senninha]

Nice but I think I will stay with 16/17 combination, and try to get a twin 5 spoke wheel....these ones start at 17"

Mmm, me suspects you're not a committed modder, LoL

16/17 would need very careful style selection otherwise they could a) look smaller than OEM b) have poor offsets so look further tucked into the arches c) possibly restrict tyre choices and d) leave you wishing you could lower the suspension as it could end up looking like an NSX 4x4 ...

If you're not keen on 17\18, then as Andrew suggests, maybe consider 17\17

[Sudesh]

I'd also consider larger wheels, but only rim for me is prodrive GC-O7C, for now though other more important project to attend too.

Ok, OK you win.....I wanted to stay with the 16's and 17's so I didnt mess with the handling or the traction control as per posts on earlier discussions about upgrading wheels. But the choice of 16's and 17's is poor and I cannot get the (AEZ Portofino's or ENkei RSF5's) twin 5 spoke style that I want so 17/17 or 17/18 it will have to be. I'm off to research them now. Question.....

I have 16x7 et55 and 17x8.5 et 60. What size do I do for??? I found this website and below are the sizes it says I could go to:

ET = 40 mm











Rear Rim size:

ET = 45 mm



Rim type:

alloy



Remarks:

What do you guys think?

[Senninha]

What you propose should fill the arches a bit, but for a fuller option you could go with 18x9 35mm with the 17x8 +38mm ... this would give the stance in the earlier photo ... tyres 265\35 rr and 215\40 front and you'll get no TCS issues as this is the same as 17/18 Enkei set up I was running last year ... mine are not twin spoke but NA1R style so probably not of interest

Those combinations result in a speedo error of 0.3% on the fronts and 2.3% on the rears is this difference between front and rear variance an issue?

I do wish Americans would learn to spell though!http://www.rimsntires.com/specs.jspPaul, how do you think 18x8 with 215x35 et 40 would work on the front. According to the URL above it compares well with the NSX std front 16x7 et 55...How do you think it would handle, TCS etc? I would have 18x9 or 9.5's on the rear

Wheel I am looking at is the TSW Mirabeau

[Senninha]

Whilst 18's all round would work there are two considerations in my view ...

1. the front 35 profile will be VERY low and offer little wheel protection and I would be surprised if you didnt end up replacing front tyres due to excess pothole damage causing tyre damage such as splits / buldges
2. due to low profile fo front tyres, high risk of wheel damage
3. 8" fronts and you need min 9.5" rears to enable tyres (265) to sit properly on the rim

the 40 offset still keeps the rim inside the arch, on 18's you would be pushing the limts at 30 and probably need to roll the inner arch to avoid bodywork damage IIRC

Happy hunting, Paul
