I need to lower my car and upgrade the shocks/struts/springs. So far I have Hotchkis sways, TRD strut brace and the Ingall's rear brace.

My goal is the best handling possible. Secondary goal is a reasonably comfortable ride.

The systems that I am most interested in are as follows:

1) Koni shocks, Eibach Springs, Ground Control coilover sleeves
2) Buddy Club coilovers
3) Progress coilovers
4) H&R coilovers

My previous car had Tein SS on it and I liked that setup a lot, but I am looking for a little higher performance than they offered.

Koni's are nice but just have a "name" to them, like Bilstein. They work very well (on some vehicles), but you pay a lot for them through marketing. I'd go with Progress or one you haven't mentioned, Tanabe Sustec Pro Series (I is for street, II is for autoX racing).

I wouldn't go with progress. They rust.

^^^ that's one of my main concerns with them .... also, the spring rates seem a little soft.

I wish we could get Bilsteins!!!


..... so Sustec II's would be good for spirited street use, or too hard?

Not many people on here have full, adjustable coilovers on here. Sustec Pro II will be pretty hard for normal driving. But, if you don't mind a harsh ride, then they would be really nice for street/track/spirited use. Pro I would be nice to have an aggressive setup for street use and still pass at the track pretty well. I think the Pro I would be the best setup for spirited street use.

So Pro I will handle the best of the options listed and also the D2's that I've been reading about too?


Comparison at this point:

1) Koni shocks, Eibach Springs, Ground Control coilover sleeves
2) Buddy Club coilovers
3) Progress coilovers
4) H&R coilovers
5) Pro I coilovers
6) D2 coilovers


Also, given the limited responses on coilovers, I'd imagine that nobody here has any experience with KMAC camber/caster plates???

^^Probably.

I know of one member that has the TEIN coilovers with the control box but he's not online much anymore. His screenname is greddytc05. You could try sending him a PM for more info. Also, there is a for sale thread here for the D2's but I think you are already aware of that.

My problem is that I can't get any kind of comparison. I've had Tein SS before and it performs very well, but it's not a top notch suspension IMO. I'm looking for max handling. I'd like to not get too stiff of a ride either since too stiff tends to slide. A good balance of stiffness and give get the best skidpad numbers. I used to play around with the teins at higher than recommended stiffnesses. I normally drove the accord on 10 in front and 8 in the rear ..... track settings.

If you want to go beyond the capabilities of the Tein, you'll need to start saving up now to have a setup built. If you want pure performance, talk to Dan Gardner (adg016 on SL) and Rick McCallum (raamaudio on SL and YSTC) to see what exact setups they used. They both built track cars, they'll have good info.

So you think that Tein is the best aggressive street setup made for the tC?

It is a DD, but my goal is about 1.3 g's .... I know ... gonna need the KDW's for that, but I want the suspension capable of doing it.

Seeing as the Tein can be revalved, and they make springs in .5kg/mm steps from 3kg/mm all the way up to 20kg/mm, I don't think there's a more adjustable setup out there.

You will also need big bars (Hotchkis), adjustable front and rear endlinks, rear camber links, serious performance tires, not just KDWs (Like Advans or RE01R)... and most importantly, proper suspension tuning, including corner balancing.

I see .... you are talking about custom selections .... I meant the SS kit that was pre-built. Other than the tire change, I'm already planning on doing everything else .... possibly with the addition of KMAC camber/caster plates in the front.

The tires that you mentioned are better than the KDW's? They seem to have very similar reviews .... the KDW's I've experienced, the others I haven't.

I have Hotchkis bars, Ingalls rear brace, TRD strut bar, ES poly master kit, ES poly engine and tranny kit, custom ETD.

I plan to relocate, shrink and lighten the battery, Dezod endlinks, replace the hood with CF ..... perhaps fenders and doors if $$$ allows. Also, a buddy might be making a custom lower brace for me too, similar to an X-brace or ladder brace.

The best setup that has been proven with numbers have been pRogress all around, with a 1.38inch drop, sways, and corner balanced.
There is an article you can search for, I have posted it on this site many times.
They had the tC pulling the same skidpad and g's as an EVO at that height!!
Just remember, lower and stiffer, isnt always better.

If you want the absolute BEST, you need fully adjustable, corner balanced and correct camber. (this will sacrifice tire wear BAD tho)

You need to look for what you truly want. You said you are looking for the best, but I am thinking you wouldnt be happy with it, or ever need it on the streets.
The best, HKS COILOVERS.
The price, ~$2000

Are you really ready to spend that much for the best, just to have a car handle far beyond what you would ever ever need on the street?

Here is the article:

http://www.sportcompactca...cion_tc_part_1/index.html

Is it the best? I dont know.

But its the only time that actual numbers have been posted to show how well a setup has done.

Numberwise, the upgrades appear to have paid off. On the skidpad, the stock tC circled at a very Camry-like .82g. After the suspension mods and a set of 17x7-inch, 48mm offset, 5Zigen FN01R-C wheels and 225/45-17 Kumho ECSTA MX tires, the tC produced an impressive .91g. Slalom numbers also improved dramatically. The stock tC only mustered 66.1 mph but improved to 71.9 mph post-bolt-ons, which makes it only .4 mph slower through the slalo

Hmmmm .... I forgot to list them .... I was thinking about those too. The price doesn't really scare me ... and yeah, I want more handling capability then I'll ever be able to use on the street. My last car could hold a 0.9G turn and I hit 0.95 a few times measured on an Escort GT-2. This was with a 3800 lb. accord sedan and I want more!

BTW - If you think the $2000 price tag is steep, the KMAC plates are about $500 for the front set!

Why wouldn't I be happy with the HKS setup? It has adjustable shocks, so it wouldn't have to be too stiff all of the time.

So your doing this for a race course setup??

It will be stiff ALL the time. You cant just get out at a stop sign, adjust your height, dampening forces, camber and corner balance it and go whenever you want too. To get it to maximum grip, (which personally I think would be way to harsh for daily driving), is going to take hours of adjustments and trial and error.

I am not knocking what you are trying to do. You just have contradicting statements.
You cant have a comfy non harsh ride, and the BEST performance a setup can possibly give you.
You can have a decent ride, and a good performance. And thats what I would go for.


Only reason I said you wouldnt be happy with the HKS is because early on you were talking affordability. When HKS is brought into the bunch, affordability isnt mentioned.
I do think you would be happy with what the HKS can do performance wise, but for street applications, I dont think you would ever tap into their full potential.
They have 30 way dampening and rebound adjustment on them, this isnt a, hmm lets adjust this and go type of thing.


If you want something adjustable on the go, try the Tein SSp with EDFC. You cant adjust the ride height, but you can adjust the dampening forces from inside the vehicle.



(oh and something to point out, there was just a thread on hear about Nick Hogan complaining how he paralyzed his passenger. Anyone that is looking to get .9gs on the street is just as bad as him!!)

I don't know if a desire to get good handling equals being Nick Hogan. That guy was born an idiot. Either way, .9g isn't a whole lot. I can do better than that with 245s and the TRD kit.

But the desire to do it on the street puts you in the same class of stupidity. .9gs while nto alot, is alot more than should ever need to be reached on a street.

The tC pulls .82gs STOCK. To get your car out of control around a turn on the street (to break that .82gs) you will be driving EXTREMELY faster than what the turn should be!!!
