I just received the CoilOvers that I had ordered earlier this week.

They are made by a company called D2 Racing.

Here is link -

In the manual it says: "this part is not to be used on the street."

My question is this: My RX-7 is a daily driver. What does the above statement actually mean? Or a better way to ask is how should I

interpret what the manual says?

Am I risking my life with these CoilOvers installed in my RX-7 by doing daily driving. Especially, since I do do a lot of highway driving.

Why does it say in the manual "this part is not to be used on the street."

I know we all take pride in our RX-7s but more than anything else I want to keep myself safe on the roads.

Thank You.

Should have spent the extra money and got a better set of coilovers, you are going to be kicking yourself a couple of months from now.

My assumption is that it is for legal reasons. A lot of companies put "for race use only", my authentic re-amemiya hood has for race use only stamped on it, and its a hood.

 

it's just because the coilovers are not oem like the factory shocks.

Why would you say that? Do the de-grade over time?

 

No (well, yeah, but not for a few years at least), it's just that those are basically eBay coilovers and haven't been tuned for our Mazda so you'll probably not have the best ride quality.

The sticker's there because the coilovers haven't gone through any (insanely expensive and time consuming) highway safety tests by the government, like most aftermarket car parts. I'll bet your intake has the same sticker...I know mine does, as do the Zeal coilovers on my FD.

 

Its probably their way of getting away from any warranty claims and returns. Doesn't that make you feel all warm and fuzzy?

What are you going to do when they blow and they don't have any service facilities to work on them at a fair price? Koni offers a lifetime warranty on their shocks for example.

 

Virtually every aftermarket part you buy says "for offroad use only" someplace, and this sounds like a rough translation of that. It's just cover your *** legal boilerplate.

 

Thanks, that's great info to know.

They are not EBay. I actually got them from www.nolimitmotorsport.com

Paid $890.00 for them.

 

you will regrett buying them, i got so sick of mine i threw them in the sea,
they are about the worst thing you can put on your car,
they are actually worse than blown stocks.
your car will bounce around on the road lice crazy (adjustability my ***)

 

Were yours D2 also?

Hopefully, I wont have to throw mine in the sea. Because where I live there is no sea nearby. About 4 hours away to get to the sea...

 

He also replied in your other thread:
https://www.rx7club.com/suspension-wheels-tires-brakes-20/would-you-recommend-these-coilovers-845023/

You had a whole thread of people suggesting not to buy them. I think you made a mistake with this purchase and you would have been better off with the options we discussed in PM's.

 

Probably a shorter distance if you fly there?


Reading that thread, not one single person reccomended those coilovers, yet you decided to get them anyways?

 

Mahjik and PureRX7,

Thank You for your input.

Mahjik, when I made the decision to go with these CoilOver as opposed to what you had suggested.

1. Tokico Gas Shock Strut Set.
2. H&R Springs.

I took very much into consideration your emails /PMs and I please believe me when I say this. I felt like I had gone against your educated and experienced decision. Mahji, you know that I have come to you many a times asking your valuable input.

The Shop that will be doing the install for me is very professional. I have dealt with them before and they are top notch. They suggested to me that CoilOvers would be a better option because you will really be able to level your car exactly. Level meaning front and back the exact same length.

I even showed them the Tokico Gas Shock Strut Set and the H&R Springs and was ready to purchase but they told me that CoilOvers would be a perfect option.

At this point, my goal is this. I'll first have the Dunlop Tires installed and then take the car and have the CoilOvers installed.

I'm hoping that I'll still be able to seek your valuable advice in the future.

I think the shop that I am working with will come through.

Would still like to read your thoughts after what I have written above.

I'll be honest with you. In my humble opinion I feel there are 3 people on this RX-7 Forum that really know about the RX-7 inside out. I've listed them in order below. With Respect.

1. Mahjik
2. GoodFellaFD3s
3. PureRX7

Thanks.
Nadeem

 

Being able to "level" the car at the cost of ride quality is not a good trade-off IMO. The Tokico HTS is going to be a superior damper compared to what you are going to get with the D2's. Hopefully, you'll be able to dial the suspension into something useful with those coilovers.

 

Nadeem, I appreciate the kind words, but I am no where near the top 3 and don't belong alongside Mahjik and Rich - mechanically speaking. I can guarantee you, I know more about parts and what was/is available, but I highly doubt my mechanical knowledge is even in the top 50. I can hold my own, but I could not rebuild an engine by my-self. I could however tell you every single manufactured part my MazdaSpeed or Knightsport, I am more like a human catalog of rx7 parts.

On that note, I would not say our concern is on the installation but the quality of the product. D2 and Megan products are both made in the same manufacturing building in Taiwan, and Taiwanese products are very poor quality. Who knows, maybe you will luck out, I do know a lot of s13 guys who use Megan products with great success. As Mahjik previously said, you were better off with the strut and springs, if you wanted the ability to adjust how low to go you could have gotten Eibach ground control springs.

 

my cousin used D2s in his nsx and they were all around good, ran them for 2 years without a problem until he sold the car. I cant speak for FDs though..

 

I agree with Mahjik, as usual.

"Level"ing or corner balancing an FD is only important for race or heavy track use. The car is almost perfectly corner balanced / level stock. I have posted my corner weights various times when using the H&R springs with Konis. The ride height is almost identical side to side when you add driver weight.

Don't confuse someone [at a shop] speaking with confidence with someone speaking with knowledge. The forums aren't always right but neither are the shops sometimes (or many times depending on how crappy they are).

Either way, do what you want at this point. If you install them, you at least get the experience of coilovers firsthand.

 

I'm flattered to be on your short list, but I'm certainly not all-knowing when it comes to these cars......just been around them a long time, and like to share the things I've learned.

IMO, you should have never gotten that particular brand of coilovers.......rather something like Tanabe or Tein. If it was my car I wouldn't install them.

 

hellyes they where d2.
not only did they **** upp the ridecomfort
but allso the handling. down right dangerous, they made me hate my car.
when i put stock bilsteins and tein springs on, it was like coming to heaven
pleeeeeease dont ruin your car with d2, those shop guys doesnt seeme to know **** about coilovers if they recomend that crap.

 

for that much money I would have spent a bit more and got BCRacing coilovers for 950$

 

your shop was right in the aspec of coilovers > shocks but when ebay brand vs reputable brands name come in play it changes things...

 

Cut your losses. If they are not installed yet, don't spend more money down a hole getting them installed.

 

Return them, eat the shipping costs, go with a fully rebuildable and reputable set of coilovers designed for the FD.

If you don't track your car regularly, and since it is your daily driver.... I would go with the aforementioned strut/spring combination. You won't like coilovers for a daily driver. And if you don't track often, you won't ever really use coilovers either.

 

I think Damian and Dale Clark oughtta be on that list, and the list should be much longer, because there are a TON of knowledgeable, helpful, and downright cool guys on this forum.


...and you should have bought those Zeals for 800 bucks.

 

^shipping on those Zeals was like $350, so they were really $1150. Either way, would have been a MUCH better choice then the D2 coilovers, even though the zeals were used.
