Suspension Setup Question

[Ran Kizama]

So I have the following setup being put on the car this weekend.

17x7 Buddy Club Racing Rims
205/40/17 Falken Tires
TRD Shocks
TRD Springs
TRD Rear Anti-Sway Bar
Tanabe Front Strut Tower Bar

Any ideas on what I should be expecting? Too stiff? Not enough? Just trying to predict any changes or modifications I should look into. I thought about the C-ONE Front Anti-Sway Bar and underbraces, but I think I'm gonna wait and see how this works out first. Thanks in advance for all tips. :smile:

the Sprotivo shocks aren't dampened too high. i have that with the S.Tech's and the Tanabe strut bar. i can feel the bumps and imperfections of the roads, but that shouldn't be the case with the TRD Springs. aren't those progressive? shouldn't they provide a near stock ride over bumps until you start cornering?
but the big difference would probably be the rims. my cousin had 17's or 18's on his SW20 (don't think it was lowered at the time), and i can feel the road on my ass.

but for me, my set up is a little too soft for me, but hope you like yours.

[Ran Kizama]

Well, I almost went with coilovers, but decided that I didn't want race stiffness while daily driving. Yeah, the TRD Springs are progressive so they'll get better the harder I push it. The wheels I'm getting are the Buddy Club P1 Racing rims so they should do well. We'll see.

I'd leave the rear sway bar out. Sell it. Your car is going to oversteer with that suspension setup. Find a front sway bar.

[Ran Kizama]

That's kind of what I was fearing, but coming from a RWD turbocharged vehicle, I'm a lot better at dealing with oversteer than understeer. Also, the bodyroll has to be dealt with somehow. Am I going about this the right way?

[ChinoCharles]

Body roll will for all intents and purposes be eliminated with those shocks and struts. They're pretty stiff, but not so stiff that it makes it impossible to drive them daily. You're right on track man, your shit will rip. Install everything but the bars and drive on it for a few days. Then throw the strut bar on and see how it feels. You may or may not want to try the rear sway bar, but from what I have come to understand about the function of sway bars that particular bar shouldn't provide any benefit over TRD suspension components. You'll want to work on the front.

[Ran Kizama]

Thanks Charles, I'll keep that in mind. Seeing as how the rear sway installs and uninstalls in about 10min, I'll do a before and after ride down my local twisties* and let you know. :smile:

Local Twisties = 10 mins from my house. 12 miles, 1.5 Lanes Wide, Very Curvy :biggrin:

NIce nice...

:'( im so broke......wait im getting paid tomorrow again! yay ^_^

Will get was thinking of getting tanabe but again, im always on the highway :/

Can't go. I was actually scheduled to leave May 12th, but recent events are keeping me at home until next summer. Which is exactly why I'm splurging on performance parts. lol

i agree. any suggestions for a stiffer FRONT sway bar ?

[Ran Kizama]

The only front bar I've seen is the C-ONE bar and it's about $350. That's the only reason I didn't get it. Maybe next paycheck with the TWM shifter.

[Blenjar]

Or just hold off on the rear sway ar...keep it till u until both together.
IMO

[Ran Kizama]

Does anyone except C-ONE make a front sway bar?

[ChinoCharles]

I'm not sure, but an e-mail to Progress Tech never hurt.

He definately won't oversteer with the rear bar only. There is so much understeer built into the car the rear bar will bring it closer to being balanced. Adding the front bar will again put in more understeer. For a street car, a rear bar only will be good.

If all you do is drive on the freeway and put around town there is no need to even get any bar at all.

[nurburgring]

If you drive hard... bring the camber down to -1.8" . I'm doing -1.5" just to save the tyres. It is a great world of difference when fighting understeer. U feel the car being more direct as u ride less on the sidewalls.

I cant wait to see your buddy clubs. I have the replicas and I think they look fantastic. But Mine's in 16".

I find the car not very understeery for a FWD. In fact, the rear seems abit unsettled. There is just too little weight behind.

Ashley, I trust your word but I disagree with this post... could be a miscommunication or it could be that I'm a novice. Help me understand.

When I take a hard, sweeping turn at a high speed, the first thing I lose is always my rear tires. My fronts stay nicely planted. Knowing this, why would it make sense to have a rear sway bar? Wouldn't you want a front sway bar so you're increasing understeer relative to the oversteer already experienced?

yea you are right

Wouldn't you want a front sway bar so you're increasing understeer relative to the oversteer already experienced?

You are right, but our cars are set up a bit different. I don't have the rear stepping out on high speed turns. My rear stays hooked up. This is probably because of my upgraded tires. My front scrubs off a bit at speed, so the rear bar only would get it to rotate a bit better.

All cars are set up to understeer as stock. That is why you see so many rear bars for all kinds of cars.

A dumb question then, if someone wanted to simply control body roll, would a rear anti-sway bar do the trick?

Yes it would help.

[Ran Kizama]

Woohoo! All my parts came in today! Taking off work early to knock out the install! (>^_^)>

Hello RAN!
Please you post TRD Rear Anti-Sway Bar and
Tanabe Front Strut Tower Bar picture or send me by PM.
I need this part! So cool!
Thanks in advance.
:w00t:

[Ran Kizama]

The parts got installed yesterday. I'll get some pics up here in a few mins. The rear swaybar took all of 10mins to install and the front tower bar took maybe 15min since you gotta adjust the bar, brackets, and tighten everything down.

Overall I gotta say that the car feels fantastic! The corners are stiffer and the car's understeer has definitely been reduced. I noticed this primarily on a specific corner on my local twisties. There's no real signs of oversteer either which is a plus. I gotta say that the biggest bonus is the elimination of the body roll. I'm so happy that my car doesn't feel like a minivan anymore. :biggrin:

I'm getting new tires and a full alignment on Monday, then me and some friends are hitting the mountain next Sunday. I'll let you know how it goes. :smile:

[Ran Kizama]

Pics of both bars and brackets. Each bar is only held on with only two bolts on each side. I took a pic of the brackets so you can get an idea of how to install each one.

The TRD Sway Bar uses the stock shock bottom bolts and a new bolt on each side to connect.

The Tanabe Strut Bar uses two new bolts and nuts to connect. First you measure out the length to ensure all four holes line up. The place the bolts through the top and down into the wheel well. Reaching into the wheel well to put the nut is kinda annoying, but not hard to do. Do this for all four bolts, tighten them up, then tighten down the bolts on the actual bar, and you're good to go. :smile:

Looks sweet dude....i'll be getting some of this stuff too...over time though...heh heh my payment aint that big... :smile:
TRD struts and shocks next week!! Whoo hoo....thanks Chino...LOL
