nismo or agx & RSR: need help after research.

[glitched]

Ok, after spending ALL evening researching this crap this is what I have come down to.

I currently have Tokico blues and ebay cheapo coilovers (See other thread if you must)

First I was looking at coilovers, specifically Stance. - to expenive/stiffThen i was looking at koni yellows & RSR race springs - install issues, still kinda stiff and expensive, race springs to stiff for anything but koni... SOThen I was looking at Nismo S-tuned - great price from midway, matched spring struts, but not enough drop, would actually RAISE my car.

Now I'm looking at Kyb AGX with some RSR ti2000 springs. The struts are adjustable and these springs seem to be new as I cant find much info on here about them. But they have the same stats as RSR down springs, but lighter and stronger. http://www.rs-r.com/products/suspension/ti2000.php

SPECS:Nismo 685 shipped from midwayFront:Rebound: 353lbfCompression: 160lbf5.34 kg/mm 1 in drop

Rear:Rebound: 323lbfCompression: 124lbf3.75 kg/mm .6 in drop

AGX&ti2000775 shipped from intense and tirerackFront:adjustable ~115-2233 kg/mm1.6 in drop

Rearadjustable ~115-2233 KG/MM1.2 In drop

So based on what I have foundnismo (uses KYB)plus: Price, matched set.neg: drop, non adjustableVSKYB & RSRplus: drop, adjustable.neg: unmatched set

And of course the price difference goes out the window if i just get RSR down instead of the ti2000 springs...

Both will be quality nismo vs top of the line RSR springs, both use KYB shocks.

Unkown: (affected by spring rates/dampening/matched sets)wich would be better performancewich would be better ride quality.

Ive also emailed rsr asking what struts they would recamend with the ti2000 springs IF not the AGX's

can anybody else think of pos/negs of each setup? instalation issues? (hopefull easier than koni inserts) comments suggestions?

I have RS*R Ti2000 springs. Note that they are progressive. I didn't find that out until after I got them, but I got a really good deal on them anyway. I've got them paired with some KYB Sr Special shocks. Not adjustable, but stiffer than the gr-2's. Ride drop was good. I still have some gap, but it's not that bad. Handling is pretty good so far as it doesn't ride super stiff, but it's not a marshmallow either. It's got a firm feel, much more so than cars I've ridden in that were using eibach or tein springs. A nice setup for the street. It wouldn't be the ideal setup for drifting or an autocross, but then again I'm not doing either of those at this point.

You seem to have covered your bases with both options. I think teddy hit on something with the progressive rate RSR springs. If you are going to be doing any driving on the track, the linear rate springs of the Nismo pieces might be easier to drive on.

I know there are a few folks on here who have Nismo S-Tunes and really like them. I don't know of anyone using the RSR ti2000 springs, not that it means they're a bad product.

[glitched]

well crap, the progressive will probably deture that out for me (why i wasnt looking at s-techs)

1. are all 3 models of RSR springs progressive?

2. Are you sure the NISMO are really linear?

3. Anybody know if tanabe gf210 springs are linear or progressive? I just sent an email to em asking about that, I'll let anybody know what I find.

4. Is Rico05 still around? Ive seen that he has been a big proponent for the s-tunes, I wonder if they have settled any more since he made the comment about ridehight a while back...

Im reallying thinking around 3kg springrates at 1.5in drop is what Im looking for.

The RS*R race and down are linear, Ti2000 are progressive. Tanabe GF210 are linear as well. Rico05 is typically in the CA section, but if you email him he'll probably respond.

Why don't you look at the ksport coilovers? A lot of people on here have had good experiencese with them without breaking the bank.

[glitched]

I'm thinking coilovers are out of the question period, (even if i did get coilovers I wouldnt get the cheapest i could find. i would spring for somthing a bit better) as I'm looking to INCREASE ride comfort over my current setup while retaining better performance than stock. I have no idea what the POS springs i have are, but its paingfully bone rattleing over bumps, no bounce, but it feels like the car will rattle apart on larger bumps.

I can see that you are going through what I went through a couple of months ago. I was about to get GF210 & KYB, but ended up getting Stance GR+ Pro. This car is on KYB and GF210 combo.

That looks great!

I got a response back from tanabe:

The GF210’s for the S13 240SX have some progressive coils for ride quality, but the majority of the spring is linear rate. Progressive coils are at a softer rate and are closer wound and provide higher comfort and traction over small bumps and road irregularities, where a purely higher rate linear spring would bounce over them. The GF210’s is a balanced spring for handling, where the higher linear rates of the majority of the spring are utilized during aggressive cornering, and the softer progressives coils maintain daily drivability.

So I'm wondering if the ti2000 is the same... Still waiting for RSR's response.

[94_240sx]

I'm telling you. I almost got GF210 and KYB. Set of GF210 was like $156+shpping, so price was very attractive too. It's a member attwater's vert. Try to search. I got some good info on springs from there too. I hope this helps...

Ok, thanks!

Just found out that the Nismo S-tune are progressive as well.

[nismofly]

best part about s-tune is the dampers are actually matched to the spring rates, much like coilovers

but if you want to be lower, no theyre not for you

i was going to get rs*r down with agx if i got springs and shocks, but i just ended up getting KTS coilovers because i knew thats what id end up with anyway...and honestly it took all of about 5 mins to get used to the ride and ive been fine with them since

you notice how soft other peoples cars are when you ride with them, but your car feels normal in no time
