ARK PERFORMANCE INC: DTP Coilover Systems For the 370z

CFZ

LOL.. I like the background research you did. And yes, good products are good products. And is there a problem with OEM replacement springs? I am a huge fan of Swift Springs, I have tested all kinds of different springs on the market and nothing tops it. Ive used Hipercoils, Eibach, integra, Afcoils and they dont get anywhere as durable or consistent as the Swifts. I have their coilover springs on all of my coilovers. The 370Z is a brand new daily driver for me, I don't see a point in putting coilovers in. I already have several track cars and I have the equipment to do everything I need to with suspension.

In fact if you were to give me one of your shocks I have a roerhig dyno in my garage along with a spring dyno as well. I have my own business but I do a lot of suspension tuning in the asphault late model market as well as a few formula cars, drag racing, and just simple touring cars. I revalve and rebuild shocks. Def not something you can make a living out of so you can call it a hobby if you'd like.
But I do a lot of different shocks like penske's, bilsteins, and JRZ's. And I also do work with several bigger teams.

Everything I said so far is an educated claim. I am just simply saying everything you are saying is unclear. I have my own shock dyno and frankly I dont see how you can even revalve your own coilovers in house without one. So your telling me that if I want to change the rates on my coilovers I have to send it to you and trust that you did it right when they are returned to me. Because without dyno sheets a revalve means nothing. I see the dyno chart on page 5 of the 350Z forum from a third party, but it's only one front and one rear.

I've tested out almost every coilover in the market, but not by feel, like you do yourself. Sitting inside a 370Z with different coils again means nothing. None of that is hard data. In fact for all I know your unbiased judgement can be all placebo effect. I have hard data on a good amount of coilovers and shocks. And of course I have driven on them as well. Not specifically for the 370Z but for S2k, Evo, Subarus and a few BMW here and there. This isn't to test out how good a coilover is for a specific car. It is to see how well a shock performs in general.

In fact I think the next step for you is to make educated asessments.
- if your going to talk about Taiwans or chinas lack of quality control, give me data.
- If your going to say your coilovers are performance oriented without sacrificing comfort, give me data
- If your going to say that your coilovers are higher quality than the other cheaper brands out there, give me data.
- if your going to claim that coilovers are automatically better than lowering springs, give me data.

I wonder if you even read what we have written so far. Nothing I have said is just words. I have pulled out pictures to show quality from simple google images. Now I havent made any other claims or anything. I never said your product sucks, I have just asked questions, but your responses...... hmmm...... doesnt make sense.

Nothing is concrete with you guys so far. Lets hope this changes.
