How much would it cost for shipping of any of your available suspension sets to Auckland, New Zealand?



Have been looking at sets here and there just isn't the range that you have. Would be interested in the Buddy Club or the Apexi possibly one of the HKS depending on shipping.



Would there be an advantage going to the HKS over the others?



Very informative thread by the way.

APEX is releasing a new suspension kit for the 93+ RX-7.



32 way adjustable

12 kg/cm springs in the front and back



The N1 ExV Damper is the newest edition to Apex's high performance street line of coilover suspension. The Expert Type V (ExV) is a full coilover suspension featuring a threaded base for precise ride height adjustment without compromising shock or spring travel. Apex have taken their street suspension to the next level by including high performance upper mounts and 32 way ride quality adjustment for street cars that are used at the track as well. The spring rates and internal valving of the ExV has been completely refined for excellent ride quality and sports driving. The ExV was designed to cater exclusively to U.S. market vehicles. With this in mind, internal components have been specifically engineered to withstand harsher road conditions and increased wear caused by everyday street driveing. The Expert Type V was developed based upon user requests for a high performance damper that doesn't carry a typical racing suspension price tag. This system stands as their commitment in providing customers with the ultimate in quality and affordability.



This suspension has a list price of $1390. Street Price is about $1100. If there are enough people interested, I can do a group by on them.



1-4 buyers: $975

4-8 buyers: $945

9+ buyers: $890!



Please post here if you are interested. I will have photos of the suspension next week.

i run and really like lots of Apexi products and i also run Chuck's toe links which are well built...



that said, being a closet suspension engineer and having road raced successfully for 22 seasons i want to make certain that potential buyers understand just what they are considering bolting on their car.



i am sure being an Apexi product the quality is high.



take a step back and consider what you are buying....



SPRINGS.



so what is the RATE?



first off, it is mis-stated as 12 KG/CM. i am sure it is 12 KG/mm.



that's 672 pounds per inch. the maximum front spring i recommend is 560 and that's right on the line of being too much spring.



secondly... if Chuck is correct, the front and rear springs are the same rate. not good on a front engine rear drive car.



the stock Fd runs 263 front and 195 rear.

the excellent Eibach Pro Kit springs are 350 front 255 rear

my RS*R coil overs which i consider tops are 432 front and 378 rear

the Tein Flex which i like are 566 front and 422 rear

lots of guys running regular racing springs generally run 550/450



the reason you run softer in the rear is that the primary challenge as to going fast in a front engine rear drive car is making the rear stick.



softer bias as to springs, shocks, sway bar and tire pressure ( 30 front 27-28 rear set cold) makes it happen.



similar rated front and rear springs will just make the rear slide around.



and 32 shock settings? i have a shock dyno and shock valving needs to relate to spring rate. plus or minus a modest amount. how do you say overkill.



finally just a word on going fast....



too stiff is slow just as too soft is. there is a common misunderstanding that you have to endure a hard ride to have a fast car. not true. it might seem fast as the car tends to react more quickly to the steering input but when you get to a corner you will find that the car is much harder to drive at the limit. that's because stiffer suspensions do not transfer lateral load any less than softer suspensions. the same force is transferred only faster. faster gives less feedback. it is this feed back early warning that allows a driver to drive at the limit of adhesion.



still don't think fast is soft? just watch a NASCAR restart. as the cars weave back and forth to warm their tires notice how much roll is in the chassis... lots.



if our cars didn't have a true racecar suspension, which they do, then i could see stiffer springs to decrease body roll... but we have double A arms that deliver negative camber gain on bump so roll is not an issue.



bottomline here is that unless you want to buy these coilovers for drifting... where the object is to slide, not go fast at the adhesion limit, find another nice coilover package from Chuck with the right spring rate.
