huh? wouldnt that just mean none? all the glass is the in passenger compartment - so that statement cant be right as I'm fairly certain sure you can do the rear screen and rear side windows. 

 

Do you mean the front passenger door glass and windscreen have to be normal car glass?

Rod ends and tube with threaded ends for rear suspension links? rod ends need to be to some specification?  tube needs to be certain material/thickness? what about stuff bought from overseas?

 

also is this kind of upper suspension pickup point relocation allowable for cert?

It bolts on, and moves the pickup points to change the instant roll centre (and lets you use double rod ended suspension links). there is a weld on the tube piece that goes across left/right but that is only for anti rotation really and has quite a large amount of weld/material so I dont see it as being particularly highly stressed - would it still need to be crack tested if I made something like this myself?

Hey Cletus,im midway through the VR4 conversion i asked about a couple of pages back. Ive discovered a potential issue though regarding the loops,in particular the 3rd one.im sure you have seen the underside of a VR4 legnum before,so you will know about how the 3rd part of the drive shaft is entirely under the fuel tank,and so no floor within the specs to bolt the loop to :/ .what would be the go with this in regards to cert??

With the wheel size amendment on certs, can I have two sizes listed so that I can have either 15x7 or 17x7 rims on the car? Car currently has 17" alloys listed on the plate but I'd also like to be able to run 15's from time to time (track wheels are 15's and CBF changing them on the day at the track).

you can get the car certed for 2 different size wheels, id have to find out if the lower price 'amendment' thing applies if you want 2 sets of rims on the plate or if it would be full price

you would have to make something work, there must be some bit of structure for the hanger bearing to bolt to, maybe you could mount the loop off that? the loop does not have to be straight across

if it was strong enough to not flex etc then i suppose it could be used. i would be careful though, there are a lot of bolt on things for various cars that claim to "make x better/improve traction/ reduce bumpsteer etc etc" that make things actually worse. to me that looks like it would make pinion angle change worse with suspension movement as the upper links are shorter than original. i dont know very much about mustang rear suspension tuning though, you have undoubtedly done more research on the subject than i ever want to haha

OOOH OOH MR CLINT!  I have a question....

 

What counts as a vehicle having been "extensively modified for motorsport use"?  I wish to change my front seats out for some that dont weigh 2 tonnes and realised i probably cant do this because they contain airbags and the vehicle isnt 14 years old.

 

So far on my cert list theres gonna be:

Adjustable rear arms

Brake calipers

Engine upgrade

Transmission swap

roll center adjusters / bump steer correction things

 

Fuck now that i think about it, i might need driveshaft loops too.  120kw to 165kw is the measured increase...

Was supposedly accepted last meeting (Tuesday last week?) just waiting on confirmation so I can continue with the process.

 

Apparently I only have 2 months before I have to pay for another process and this is eating into that time somewhat.

That can't be right - The guy who built the fully sick Cedric in Chch had his approval done for a full custom crossmember and rear suspension a few years ago and only got his cert 6 months ago.

Yeah, so normally you apply for Design Approval at the start of a project as a separate thing from the final cert process. (The two months starts from the start of the final cert process?)

 

They've had me do an approval after I have applied for the cert, during the two month period. Make any sense?

My understanding is

 

  • Project Start
  • Get Design Approval
  • Fabrication Stage
  • Project Complete
  • Apply for Cert

 

What stage are you up to?

 

 

Clint knows this shit about a million % better than me so I should shutup as I am not sure here.
