I have just finished the engineering for Jamex on the 200SX S15 Bilstein and Whiteline Suspension kits. These have been extensively road and track tested over the last 4 months in three S15’s. Similar to what I did for R32/33/34’s, they will be offered on a Group Buy from Jamex for 15% to 20% less than the recommended retail prices, plus freight will be free for all orders over $500, plus there will be an additional discount of 5% for orders over $1,000.

The Group Buy kit was engineered (by me) to give a sporty, but not harsh ride, for the street and at the same time suite the sort of things that S15’s owners use their cars for (road, drag and circuit). It’s a great all round kit judging by the comments back from the people that have tried it.

Due to the strut based front end there will be a basic kit with Whiteline coil springs. Plus a full height adjustable coil over kit utilising Eibach (the best) coil springs with Noltec adjustable strut tops as an option. Extensive engineering has been carried out on a full replacement coil over front strut which features a unique Bilstein shock absorber. Plus it allows greater scope for camber adjustment combined with the use of wide wheels and tyres.

In all cases the Bilstein damper valving has been selected (by me) to suite the spring and stabiliser bar rates used. I have spent some time engineering in an additional 20 mm (23 mm at the wheel) front suspension travel to avoid one of the major limitations of the packaging in an S15. This means I could use a lower spring rate for better handling and ride and, at the same time avoid the bottoming out issues that frequent lowered S15's The Bisltein front struts incorporate an internal bump stop which has been rated and sized to suite the rest of the kit. For better control of dynamic camber and caster, the Bilstein front inserts feature the inverted layout which results in far stronger resistence to the bending forces that struts have to endure.

The rear Bilsteins are of course full shock replacements and the Whiteline Bump Stop & Dust Cover kit has suggested trimming heights as follows;


There is a full set of suggested alignment settings (including ride heights) for both road and track use, which are designed to optimise the handling and avoid excessive tyre wear.

Table of alignment settings

Recommended Road Settings
Front
Caster = 7 degrees positive (slightly more on the LHS to counter the drift to the gutter)
Camber = 1.25 to 1.5 degrees negative
Toe = Zero

Rear
Camber = 0.75 to 1.25 degrees negative
Toe = In 2 mm each side

Recommended Circuit (grip) Settings
Front
Caster = 8 to 9 degrees positive
Camber = 2.5 to 4.0 degrees negative
Toe = Zero

Rear
Camber = 1.25 to 2.0 degrees negative
Toe = Zero

Recommended Drift Settings
Front
Caster = 8 to 9 degrees positive
Camber = 2.5 to 4.0 degrees negative
Toe = Zero to 1 mm toe out each side

Rear
Camber = 0.75 to 1.0 degrees negative
Toe = Out 2 mm each side


Recommended Drag Settings
Front
Caster = 7 degrees positive
Camber = 1.25 to 1.5 degrees negative
Toe = Zero

Rear
Camber = 0.25 positive to zero degrees (never negative)
Toe = Zero


Price Lists
The Road Kit is designed for daily sporty driving and is suitable for occasional circuit, drag and drift work. Although an upgrade to adjustable stabiliser bars would be recommended for those willing to tune the handling for their personal preferences.



The price lists reflect a saving for SAU Group Buyers of $678 (around 25%) over normal retail prices.


The Road & Track Kit is suitable for road driving, to and from the track and other weekend work. Several of the guys during the testing have commented that they could easily live with the Competition Kit as a daily driver. The stabiliser bars are, of course, adjustable, plus the springs and damper rates are not in any way excessive. The recommended alignment settings are a bt extreme for daily driving and would result in excessive tyre wear if large numbers of kilometres are driven. The Road & Track Kit is priced the same for Drag, Circuit (grip) and Drift users. The spring, shock and stabiliser bar rates being the difference. So please specify your usage patterns when ordering.




The price lists reflect a saving for SAU Group Buyers of $1,215 (around 25%) over normal retail prices.

PS; The S14 Group buy kits are now open, for S13 (CA & SR) owners, their kits are currently being engineered and will be released shortly

Register on the forums for fewer ads.

prices??

Ah damn SK. I wish I knew you were going to develop something for the Silvia chassis! Bah splurged a heap of cash on some Zeal coilovers only a few months ago (mainly to address the issue of lack of front suspension travel). What spring rates have you decided to go with?

PS If you have this going on ns.com it would be hot cakes... if you need assistance I'll be happy to as I am a sponsor mod.

I too am interested in this setup, as I'd rather a well setup coil and shock than all the fancy height/damper/rebound/kite flying stuff that some other designs have. I'll only want to set the height once, then leave it at that.

I've got this thread to remind me when someone replies so I can monitor it, I look forward to seeing prices etc for the S14's!!

Cheers,
Theo

Just waiting on the last of the prices to come through. They will be in the designated place in the #1 post.

cheers

Dude just in time was about to order some HKS Performers! How do you think ur package will compare with these (6/4 rates) on a hard driven street car with an occasional track day?

Based on the results of the guys currently using it, the kit will piss all over any Jap suspension. Road or track. Ask around and you will find that I don't exagerate.

cheers

Also registering my interest. I'm in the market for a new suspension for my s15

hmm waiting for s13 and also est of prices ...

looking forward to this.. any thought on how they will compare to the Tein superstreet tuned for australian roads?

drift?

i also have the same question with a bit more detail behind it.

i have a s13, which i use as my daily but also drift on track. would the s13 setup be adequate for drifting ? or is it to soft/ more street based? any idea on the spring rate?

id much prefer to buy a set of these over hsd etc.

thanks

Yes, there will be a kit specifically engineered for drift. It will feature larger adjustable stabilsier bars, which means you won't have to put up with excessive oversteer when not drifting.

Yes, there will be specific recommended drfit alignment settings.

cheers

so a street and drift one..?

SK, Any eta on that price list mate?

i already got a set of adjustable swaybars, but id defenitly be keen on a set of shocks/springs for a s13, the sooner the better as my shagged coilovers are in desperate need of replacment.

^ I can confirm the interest!

I just heard about this on ns.com and am very interested, pending pricing.

Possibly interested in an S13 track biased setup if one becomes available

Dane

Last prices due in today, so the S15 kits should be posted up late tonight.

cheers

Good, I've been waiting for 4 months.
