so my stock bilsteins with teins S-tech springs are giving out. and im looking to replace them with some good coilovers. i will be buying them directly from japan, so i have alot og options.
what im currently considering is the new HKS hipermax 4 GT or the Blitz ZZR
the hipermax is 8/8 sprin grate and the Blitz is 10/8
this is a purely street car, im getting old, and my back sucks. so i want at least some comfort
anyone got any experience with these setups?

 

Might want to look at Ohlins. I've seen some comments from people like "they made me enjoy driving on the street again." I don't have first hand experience with them other than watching a set be installed and driven away by the customer so make sure to do your research and not put much weight in my say.

 

I'm of an age where things are starting to wear more (ok 50 something) and recently put in Ohlins. I really like them, a better ride than the prior Konis with sport springs, and they handle great. But...I also autocross so am willing to compromise a street ride.

If it was a purely street car for me I'd think Bilsteins and stock springs would be great, or a mild sport spring if you want in lowered for looks.

 

For street use, just go with Tein Flex. You can even add the EDFC so you can do adjustments from inside the cockpit.

 

Those are both overkill for a street car however they are both great options. We have several customers utilizing both without any complaints, out of the two I would go with the HKS.

If you are open to other options, we have a lot of coilovers in inventory right now. Including a set of barely used Greddy Type-S which are perfect for a street car for only $999.

Ohlins DFV are fan-fricking-tastic on the street. I can't believe how well they smooth out road imperfections. For your usage, I would get custom spring rates instead of the 11k/11k they come with. I would ask for something like 9k/7k. Shouldn't have to revalve them for that, just run them a few more clicks out.

FWIW, even on the street I run mine at only 6 clicks out (out of 20). The recommended 10 clicks felt a little underdamped to me even for street usage. At the track I wound up at 4 clicks front, 5 clicks rear and it made a noticeable difference, on the track and on the street for the ride home.

I don't think you'll find coilovers better suited for real-world street usage.

 

hmm. i would like to have the Øhlins, but they are more than 2x as expensive:S
if i chose the HKS`s, where could i get custom springs?
8/6 would suit me fine (as long as i wouldn't need to re valve the coilovers for it)

and Pure RX7, i appreciate the offer but i shop the same place as you do (+ i get free shipping this time) so you couldn't possibly match the price

 

Figure out what you can get serviced as closely as possible (dampers are going to fail or need rebuilding at some point). That will help determine what would be a good fit for your needs.

 

yeah Mahjik. thats going to be a problem with any coilover brand. since i live on the north pole i cant get anything serviced in country.
thats one + in the Blitz`s favor. they just swapp out the damper unit and throw it away, no rebuilding needed

 

A damper body that's so low in value that it's a throwaway isn't likely to give either desirable or consistent damping characteristics!

Ohlins is in Sweden, not too too far from Norway, right?! DFV are made in Japan, but I'm sure they could be serviced in Sweden, for sure this should be the case if they sell DFV there.

IMO, 8/6 springs should work fine with the stock DFV valving, based on my "optimal" street settings of only 6 clicks out out of 20 with the standard 11/11 springs. With 8/6 springs, you might end up at something like 8-12 clicks front, 10-14 clicks rear (guessing).

Worth noting that damping values to maintain the same %-age of critical damping changes with the *square root* of spring rate, not linearly. So if you go with 6kg springs (.55x standard 11kg/mm rate), optimal damping will be square root of .55, or 0.74 of the original damping. That's why dampers can usually work well over a broad range of spring rates.

If I were going to stiffer springs, I might revalve. But going softer shouldn't be a problem, even down to 6kg/mm from 11kg/mm. You should easily be able to accommodate that with the standard damping adjustment range.
