please can you help me on which suspension to choose from the cheaper d2 or the more expensive tein super street for my evo 4. i will be using the car on the streets mainly as a weekend special, i also have plans to make the car capable of making 600bhp. any suggestions will be appreciated

 

Here this might help you out...

I just switched from the HKS Hypermax coilovers to the D2s last weekend.
The D2s are half the weight of the HKS just for starters. So if your looking at saving weight this is an option. As for the drive the D2s ride pretty good. I have had to adjust the settings on them a few times now to get the right rebound im looking for.
The Hks coilovers ride a hell of a lot better thats for sure.

If I were to buy either or, it would depend on what you want. A good race application- D2s, over all quiality & comfort HKS.
Just mt 2 cents.

 

It is possible to have both great on track performance and high quality + street comfort.

One sign of a good race shock is that it still rides relatively well with medium spring rates.

i would say the hipermax's or the tein's...

i have tein ss-p's on my rsx right now and i love them

 

Why not just a good spring and shock combo? You could get much better dampers this route.

 

I ordered a Stance setup, installing it tomorrow. I had teins on my eclipse, so ill at least be able to compare the Stance set to something similar.

btw, I ordered the Stance GT+ Pro

 

Here is something to ponder;

The D2 has seperate adjustment for height and compression. while the Tein SS has to be adjusted via the shock body, so when your car goes down, compression goes up. Plus D2 has 36 way damper adjustability compared to only 16 that Tein offers.

 

I completely agree. Most Teins are steel housed, and have welds. The D2s sit inside CNC Anodized Aluminum housing. Absolutely no welds.

I switch from a set of Tein Basics, mind you these are the lowest level of Tein C/Os for my 350z; I sold within one month due to poor ride quality, shoddy perforance, and overall quality, fit, and finish that left me disappointed, and with a feeling that I had just been ripped off. For the price of the Tein Basics, the D2s have all the features - and more- than coilovers costing double their price.

Problem is that rebound and compression are adjusted in a single simultanoues turn (either increase compression and decrease rebound, or the exact opposite), therefore you're limited by the amount of "fine" tuning that can actually be acheived.

Still highly recommended and might even be a future mod for my daily driven 9 MR, problem is, I have been spoiled by JIC. Simply put I have not found a set of coilovers that offer increased spring rates and dampening, while still being able to offer the occupants a ride that is sure to be confused with something other than race.

 

1. Compression is not the entirely correct term to use. It is height and stroke. The adjustable lower mount allows you to adjust ride height by changing the overall length of the coilover, instead of raising/lowering the spring perch to adjust height, which reduces available stroke. Doing so doesn't reduce or increase "compression", your compression damping remains unchanged. What it does change is the amount of available stroke you have before the piston bottoms out during compression.

2. No damper has any more than 4 ways of adjustability, let alone 16 or 36. You can have an infinite number of *levels* of adjustability (eg. Koni), but there are only 4 commonly accepted ways in which a damper can be adjusted - low speed rebound, low speed compression, high speed rebound and high speed compression. And what's important is not how many levels of adjustment you have, but how effective each level is at controlling the spring without being over- or under-damped. Some argue that no more than a single level of damping is needed for a well setup car.

 

I have 12k/10k D2s. They are great for the price.

 

Check out the BC Racing coilovers. They are a great bang for the buck setup.

Better than D2's IMO and on par with Teins upper range models.

 

Never again will I purchase Tein.

Here is what to expect from Tein coilovers (not applicable to all model coilovers)

Steel Construction (heavy)
Welds are abundit
Painted, not anodized.
Not servicable in the US
Expensive
Poor quality in ride, and fit n' finish.
Non teflon coated (basics) which can mean very loud coilover operation

Here is what to expect from D2

Aluminum construction
FULLY CNC machined
anodized
servicable in the US
quite operation
ride, and fit, are impressive
performance is impressive

Bottom line, I have owned JICs, D2, and Teins. For the price, nothing comes close to D2 coilovers, which are not a brand that has just entered the import scene. My experience has also taught me that the D2s are bulletproof, and while ride quality seems to continue to improve over their usage, they were really only somewhat bothersome when going on inclines. Many times in my 350Z I would lift one wheel off the ground, and thus it makes inclines somewhat amusing.

 

D2 Ftw

 

D2's are tied with K Sports as the worst dampers we've ever taken off of a customer's car in terms of construction, ride quality, performance and overall valving. I would prefer stock.
