And you don't need camber plates for those either.
Hooo ok thank u and yes i'm thinking to buy tokico's shocks or a koni yellows to do everything at same time

I don't do drift, so i don't know...
No i really dont want my car for A drift or race i just want to lower and i cant lower it to much because i use it for a daily driving is why i'm asking if i have to use camber or not cause i dont want to do something incorrect.

If it's just for improving and upgrading your street performance I would skip the Konis and go with the Tokicos. I have the Konis and the jounce is very firm which makes the street ride very choppy even on the softest setting. I love em on track days and smooth roads but honestly they aren't worth the ride compromise if it's your DD and mainly for street driving. Most folks I know love the Tokicos as well.

That's my $0.02

I did the H-Tech and Tokico. I like the look, and can adjust the ride without removing the shocks. It dropped the font, took care of the gap over the front wheels, and gave me almost 2 MPG improvement on gas mileage. I think there is a picture in here someplace of before and after.

Factory setting is always good for DD or street. 0.0 in front and -1.0 in rear. if you want better handling you could try -0.8 in front and -1.0 in front.

Been out of business for a few years now . Glad to see people still looking at this info though! If you are looking for Tanabe springs, try one of the other forum vendors and I'm sure one of them can get you taken care of.

Hey DPE, I am looking to buy the Tokico adjustable shocks and some lowering springs. I want to lower my car 2inches though and most of the springs i've seen won't get that low. What would you suggest. Coilovers could be the way to go but if I could buy the Tokico's and some springs I would want that better.
thanks

813: DPE doesn't visit these forums quite often, Phil has moved on so I think your question would best addressed elsewhere.

On thing I'm curious about is why do you want to drop it a full 2 inches? That's quite a bit.

The Tokico springs will drop you 1.5 inches. I just did it and it is too much for me.

I know this is an old thread but it has helped me out in the past so i thought i would add to it since i now have a relevant comparison to add.

I recently switched from Tein Basics to a Koni/S-tech set up. When i bought my Tein Basics it was the first mod i did to my bone stock 04 GT. I had no intentions of tracking the car or doing any autocross. I just wanted a sportier ride with the ability to adjust the ride height. I wanted the adjustable ride height because at the time i had a pretty steep driveway and i really didn't want to screw myself over and not be able to make it up lol. As it turns out the adjustability of the Basics just wasn't necessary. I could have them set to the lowest setting and would barely ever scrape, anywhere. With the front/rear overhang being as little as it is and the suspension being pretty firm i had little to worry about no matter what the ride height was set at.

Long story short i've basically become a track addict. It started with autocross, went to an occasional track day and now i try to get out there whenever i can. This made me regret buying the Basics because i knew there was much better performing suspension out there. Dont get me wrong. The Basics did a great job considering the price. I had numerous ride-alongs and instructors compliment me on my car's suspension (FYI: I also have Progress anti-sway bars and Evo-R endlinks). The car was balanced, predictable, very little under or oversteer. It was quite composed over bumps and curbing and in general was a very enjoyable performance driving experience.

BUT, like i said, i knew there was better out there. I could have just jumped on to some high-end coilovers and been done with it but i've always been curious about Koni Yellows because so many people rave about them. I also just got done spending a boatload of money on a wedding so i wanted to see if i could trade for even money. I managed to find some people who to buy/sell/trade with to make it happen.

Ride Height:
Visually the car sits at about the same height as it did on the Basics (i had them set to almost the lowest setting). At first i thought it sat higher but after loosening the control arm bolts before dropping the car and re-tightening them i'd say they are about the same.

Ride Quality:
My RX8 is not my daily driver so i figured i would go "hardcore" and set the fronts to full stiff and then set the rears to 50-60% stiff. The reality is this is not hardcore at all. Much to my surprise the ride quality is better than the Basics at this setting. Our roads are horrible too. Lots of cracked concrete and uneven pavement. I'm actually tempted to set the rear to 80-100% stiff so it will just be ready to go whenever track days come around.

Dampening:
Here is where the Koni's shine. My street tires are horrible. Utter crap. They're just terrible. The only reason i have them is because they were practically brand new and came on a fancy set of Advans that are oh so pretty These things squeal and chirp over any adverse surface, under any conditions, ALL THE TIME. They honestly feel like i'm driving around on a set of shopping cart wheels. I'm trying to wear them out so i can buy something worthwhile but they just WONT DIE!! Anyway, the Koni's have silenced these things. Sharp turns, bumpy roads, you name it the Koni's do a much better job keeping them planted on the ground. They actually do the tires a little bit of justice. The chassis is less effected by bumps too. Whether you're accelerating, turning or a combination of the two (haven't really done any hard braking or trail braking yet) bumps are just soaked up without much drama at all. I've only got in a few high speed sweepers on the new setup but there is definitely some added confidence with the Koni's. I should have more feedback in this department once i get back from the track at the end of this month. Cant wait :D

Steering:
Like some people have said in this thread the steering response of the Koni's is much crisper. It was not exactly apparent at first but once you're going 40-50+ mph it's pretty obvious. Steering response is very quick and controlled.

Conclusion:
You dont need height adjustability on entry level suspension, you just dont. On a proper coilover set up which you plan to get corner balanced and dialed in perfectly, yes, height adjustment is a must. But i really believe most Tein Basic owners will set their height at or close to the bottom which is equivalent to a set of Koni/S-techs without the added performance. So in short, if you need an entry level, height adjustable coilover then the Tein Basics are a decent choice but i dont think anyone really NEEDS that. I probably over simplifying people's needs here but i have a hard time coming up with scenarios where the Basics make more sense than a set of Koni's with a decent set of springs.

Changed the rears to full stiff and it handles like a dream. Im seriously blown away with my new found grip. It's like a new car. Still rides ever so slightly better than the Teins. I can't wait to get an alignment and slap on my R-comps and track pads.

I have a slight rattle in the rear though and I can't figure out from where it's coming from. I've pulled the rear suspension 4 times now trying to eliminate it. Ever time it gets better but its still there. Frustrating...

There are a lot of people on this board that can probably answer your question more thoroughly than i can but i just wanted to point out that the Koni's are not compression adjustable they are only rebound adjustable. But, I would guess that the Koni's compression is firmer than the OEM shocks but i dont know by how much. I haven't had OEM suspension on my car for quite some time and i don't know if there are any numbers out there for us to do a comparison. So, that being said, switching from OEM shocks to Koni's may (and i would imagine should) alleviate your problem but once you install the Koni's if you're still not satisfied with the compression setting you're stuck. I suppose you could start swapping out springs at that point if you're still not satisfied but that's not really what you're asking.

Hope that helps.
