Questions About Track Increases On A Ke70 And More

[SLW42]

Hay i'm just curious in QLD laws how much can i increase the track on a ke70 before needing an engineers cert? Because i have put an s13 crossmember and brakes, coilovers into my ke and i want to get it rego'd again with all this done is it possible? and will i need a mod plate for coilovers?

Most states only allow 20mm total track increase but you need to be 100% on what it is in your state.

Haha i think you will find that the fact that you have changed the whole front end plus engine that you will need a engineers cert. Why are you using a S13 crossmember?

The wheel track must not be reduced to less than the standard track specified by the vehicle manufacturer for the particular model of vehicle.

The track of a car or car derivative may be increased by up to 26mm beyond the maximum specified by the vehicle manufacturer for the particular

model of vehicle.

Off-road passenger vehicles fitted with front and rear beam axles, may have an increase in track up to 50mm beyond the maximum specified by

the vehicle manufacturer for the particular model of vehicle.

Just pop the cheque for my services in the mail, thanks.

i wonder though, track is measured from the centre of the wheels right?

 

so essentially you could have massively wide wheels that stick out heaps, but not have that much more track.

 

though i guess the tyre width comes into play as well.. (i think QLD can have 25%/30% wider wheels?)

 

if your worried about track with s13 stuff (which you should be, its terribly on my car) look into getting some R31 control arms, a fair bit shorter.

 

the R31 guys use s13 LCA's to gain track, so i don't see why it wouldnt work in reverse.

 

also, with the extent of the mods in your car, your going to need an engineering certificate anyway.

So just to be on the safe side get an engineers cert to cover everything like motor swap crossmember coilovers and brakes so then if i do end up putting it back onto the street it should be fine ? I'm using a s13 crossmember because i figure it makes life alot easier to drop the ca into the car rather than trying to figure out engine mounts onto a ke70 crossmember

i hear you can use RB20 engine mounts and the CA will bolt up to the K crossmember?

 

you had better consult an engineer before you perform these mods, or you may find out you can't engineer it all.

my car is track only at the moment but i wanna keep the shell and get it rego'd again hence the questions, but i also wanted to go down the silvia crossmember path to find out the floors and what not with using parts from different cars, like handleing issues, understeer and all that jazz, and if i was ever going to put a ca into a street car i would go k crossmember with rb20 mounts :P

I know in VIC, the engineers certificate is only valid for 30 days. Thats enough time for you to book into your local road authority to have the engine details updated. If its not done within the 30 days, you have to apply for another certificate at a lesser monetary rate.

 

Having said that i still carry mine in a laminated book as proof incase the police want to dispute something.

 

Maybe worthwhile checking the above out incase you go to the trouble of getting a certificate, only to have it expire before the car gets registered. However I recall in QLD you get plates for the engine bay that are fixed in place.......
