regarding dampers
hello all
well the current status of my build is that i have fabricated a book chassis, the uprights i am using are of toyota liteace(only ones available to
me), the engine is toyota 4age 20v. rear is a live axle.
now i have to get some dampers to finish up my suspension. a froind of myne is coming form uk so i have an opertunity to get the dampers.
now which one should i get,
linky
was considering these, are they any good, and what spring rate should i get, considering it will be a car engined, secondly the open and close
length.
need to make decision fast, as my friend will be flying on 20th of this month
regards

further more any idea about the weight of 4 dampers with springs, as this is the most important factor when you are traveling by air

Gaz shocks are good  if they weren't, these lot wouldn't use them
don't know about spring weights. but that looks a good price to me

I have Lotus 7 steel body GAZ shocks on the front of a 4 AGE powered book chassis,(Cortina uprights) and ali GAZ on the rear.
The steel ones are quite heavy (bought off ebay) the rears are very light.
They come nicely boxed of a size that would easily fit in a carry on bag.
If doing it again I would go for ali shocks both ends,

Hi
For best quality and valving use PROTECH. They come as standard in alloy unlike the GAZ or AVO.
For open lengths the rear will want to be 13" thats the standard fitment on all BOOK dimension rear ends. This gives the chassis a ground
clearance of around 4 1/2" at the rear. If you require a higher ride height then use a 14" open length.
The front maybe slightly different using your uprights but the standard fitment for the front is 12 1/2". this give a ride height of around
4" at the front. again if you need to go higher then use a 13" this will allow a ride height of up to 5" under the front chassis.
For springs the rear will want to be 140LB if the car is driver only use and 160LB if mainly driver and passenger use. For the front try 300LB as a
starting point.
If you are really wanting to use GAZ then buy them from Dampetech. They will specify valving to suit your application. Buying from any supplier who
just keeps them on the shelf means they have general valving settings in them to cover many applications. IE not suitable for lightweight cars such
as Kitcars.

The Protech as mentioned by Matt really are lovely bits of kit.
I bought mine from MK, but I'm sure you can get them elsewhere.
Cheers,
James

Hi
The small knob dose allow adjustment of the damping range. However the dampers that are generally supplied have a damping range that is more suited to
a much heavier car Ie light saloon/ hatchback. And usually have a ratio of bump - rebound that is too high for applications such as 500-600Kg weight
kitcars Etc.
By going through suppliers who are or employ damper engineers they can sort out a specification that will be more suited to your application and tell
the damper manufacturers what specifications to build to. Hence suggesting Protech direct or Procomp ( myself ) for protechs. Or for GAZ use
dampertech.
The majority of kitcars built are suffering with poor ride quality / handling due to the wrong specification of damper being fitted to there cars.
Hence they are running on very low settings to get better results.
Cheers Matt
