Shock numbers: Making your B110 low
March 15, 2009
It burns to see so many people running strut setups from other cars in their B110 street cars and in turn running really positive offset wheels and ending up with something over the top lame.
So to help, here’s a few part numbers to possibly make the whole deal much easier for you all and maybe we’ll end up seeing more B110′s without hideous guard gap on the streets.
At the moment I’m working on a few more options but I have some measurements of A) Standard B120/B110 front shock (Munroe), B) Mazda RX7 S1 fronts (KYB) and C) Nissan Pulsar fronts (Munroe).
I’m currently running the Nissan Pulsar ones myself but have recently added 2.5″ more adjustment into the coilovers and took 70mm out of the shock leg.
A) Standard B120/B110 Munroe Gas reflex – #363-003
Total length to base of the thread – 615mm
Length of shock leg to base of thread - 195mm
length of body – 420mm
Body Dia – 37mm
B) Mazda RX7 Series One KYB – #25-3418
Total length to base of the thread – 580mm
Length of shock leg to base of thread - 200mm
length of body – 380mm
Body Dia – 38.15mm
C) Nissan Pulsar 1981-83 Munroe GT Reflex- #25-3436
Total length to base of the thread – 525mm
Length of shock leg to base of thread - 190mm
length of body – 335mm
Body Dia – 36.9mm
As you can see the Pulsar shock body is 85mm shorter than standard. Not a harshly stiff shock either which is good for those who hate a stiff ride. Realistically if you want to go low you are going to have to compromise however.
There are other options out there, AW11 rears, VW rabbit fronts, and the rest. I’m still looking for them and will update when I have more information for you.
So for the rear I’ve gone through and found two good options for the B120 and VB110. The truck and van use a shock with eyes on both ends unlike the coupes and sedans…. so obviously don’t go getting these if you don’t have a truck or a van.
A) Munroe “Original” – #23908
Holden Astra ’02-’04 rear
B) Munroe GT Gas – #150048
Type 1 & 3 Beetle rear
I have chosen to use the hydraulic Holden Astra shock in my truck (at least its not an OEM Holden part) as it is much stiffer than the Munroe gas shock for the beetle. Running low bump stop clearances, I’m not keen for a soft rear bumping around. Previously I was running some OLD and fittingly completely worn out beetle shocks in my truck. They are a good size but obviously were worn to death.
NOTE: Push the metal tube out from the bushing of the eyes or push the whole lot out and use standard 1200 shock bushings.
As far as the sizing/measurements. I will have to get back to you on the extended lengths but both go down to about 250mm and extend to about 500 or so. Lots of travel and can go very small, just what I like.
So I hope that helps.
