so here is my question. i autocross my car and like to hit up the mountain roads, I've decided on some kw v3 coil overs. my next step is the front upper arms and control arms, and for the rear front lower link, radius rod, and toe arm(to replace spring bucket). so assuming that my research so for is correct. is it an issue mixing brand for these parts? where is a good site to find this large collection? if there is a thread i somehow over looked please feel free to post it and be a total dick about it.

 

mixing brands doesn't matter at all. look in the vendor marketplace or go to sites such as

z1motorsports.com
conceptzperformance.com
importpartspro.com

 

www.nissanraceshop.com
www.thmotorsports.com

 

one thing i would say is decide what you wanna go with. poly bushings, or bearings for the rear suspension. i would make sure they are all the same if you wanna go with different brands.

for street, go polyurethane.

plan to do any racing, autox mixed with street. go bearings. but, nvh.

 

FYI
KW V3 has OEM style rear spring/shock combo. If you're gonna replace your OEM spring buckets with toe links, you will not be able to use your KW V3 rear pairs. You will need true-type coilovers at the back if you want to delete the spring bucket.

In order to retain your OEM setup for the rear suspension while adding toe adjustability, you can use the SPL spring bucket. But then KW V3 springs are progressive so their shape won't fit in the SPL spring bucket. Therefore you need to order the linear type springs for the rear (preferably with rates that closely match the KW V3 rates. IE: approx 11kg/mm).

Hope this makes sense.

If you want my honest opinion, I'd rather go for KW V2 than V3. Extra $$'s saved can be used on a set of swaybars. V3 has both rebound and compression adjustments and if you're not very experienced at setting up such system, you could even end up screwing up your car's balance instead of improving it. Added compression adjustability is the only difference between v2 and V3. For amateur-novice drivers like us, V2 is enough.

Oh yea.. ConceptZ ftw!

Mixing brands shouldn't make a huge difference.

 

Or like most people, just run your factory spring bucket arm with aftermarket toe bolts. They only timme you really need to get rid of the factory spring bucket for the SPL bucket or various toe arm if for serious track or to get serious HellaGay status.

 

Got my Z lowered a bit on KW v2 and this is what i'm going to do.

I do some AutoX, Time Attack and the usual track days every once in a while on street tyres (maybe upgrade to NT05 and the likes in the coming few months). I think this setup is good enough for me...

 

You can mix up different brands, KW V3 is the way to go for track/autocrossing. Cusco and SPl makes some great products. let me know if you have any questions
