Shakotom Posted October 29, 2013 Share Posted October 29, 2013 Possibly a reask but am getting confused hunting for answers With transmission xmembers and mounts are there any guidelines to be aware of when making one? any minimum amount of rubber or such needed to isolate it from the xmembers? Minimum number of mounting points ect? Just wanna get it cert friendly. I am currenty thinking something similar to KKs mount on his wagon? And any guidelines for welding?

Marsh Posted October 29, 2013 Share Posted October 29, 2013 Do you need cert for drop spindles in a ute? Wanting a set for my Navara but don't want to have to cert it Quote Link to comment Share on other sites More sharing options...

cletus Posted October 30, 2013 Share Posted October 30, 2013 Do you need cert for drop spindles in a ute? Wanting a set for my Navara but don't want to have to cert it yes needs cert, and its harder than it used to be due to needing to check for any change in steering geometry- bump steer etc Quote Link to comment Share on other sites More sharing options...

Thanks in sdvance heres the engine and drivetrain standard. it doesnt tell you specifically how to make a gbox xmember but it is what we have to go off when checking the car. http://www.lvvta.org.nz/documents/standards/LVVTA_STD_Engine_&_Drive-train_Conversions.pdf Quote Link to comment Share on other sites More sharing options...
cletus Posted October 30, 2013 Share Posted October 30, 2013 What is the legalty of lightening door frames on road cars like drilling lots of holes in frame with holesaw you cant weaken the structure of the door so you wouldnt be able to go too mental with the holesaw around the door frame, like near the hinges or catch etc Quote Link to comment Share on other sites More sharing options...

I have urethane engine mounts and rubber gearbox mount. Do I need to make both the same? (I'm trying to get rubber mounts for the engine at the mo cos the urethane ones are pretty harsh/near solid) Quote Link to comment Share on other sites More sharing options...
cletus Posted October 30, 2013 Share Posted October 30, 2013 nah that has been changed, you can run solid engine mounts with a rubber gbox mount now, it has been changed in the hobby car manual but not in that ^ standard a urethane mount would still be defined as a flexible mount Quote Link to comment Share on other sites More sharing options...
chees- Posted October 30, 2013 Share Posted October 30, 2013 Probably covered sorry, but when using keepers do you need the locator rings even if they dont fit over the shock body? Thanks Quote Link to comment Share on other sites More sharing options...
Bling Posted October 30, 2013 Share Posted October 30, 2013 How will they stay aligned without them? Could be a dumb question, but I can't see how it would work. Quote Link to comment Share on other sites More sharing options...
chees- Posted October 30, 2013 Share Posted October 30, 2013 shock body is big enough that the spring doesnt move around much. Quote Link to comment Share on other sites More sharing options...

e30-323ti Posted October 30, 2013 Share Posted October 30, 2013 Probably covered sorry, but when using keepers do you need the locator rings even if they dont fit over the shock body? ThanksYes, get the correct type of locating rings. There are types that locate on the OD of the spring, rather than the ID.

chees- Posted October 30, 2013 Share Posted October 30, 2013 i see plenty of adjustables with nothing to hold the spring away from the thread, so assumed it wasn't an issue. spring fouling on shock body = fail/wrong/danger keepers without locators = fail/wrong/danger sweet that is all i needed to hear, thanks ^sweet, since everything else i've seen is fucked, is it ok to run keepers above the spring? they'd fit easily there and should stop way before anything fouls Quote Link to comment Share on other sites More sharing options...
Hachi-ichi Posted October 30, 2013 Share Posted October 30, 2013 I have a question about my exhaust. I am going to book cert soon (next week or so) but not sure if my exhaust will cause a fail because of the height it sits. On the recheck paper, nothing about the exhaust was mentioned but it still hangs rather low. Will this be an issue? Quote Link to comment Share on other sites More sharing options...

On the recheck paper, nothing about the exhaust was mentioned but it still hangs rather low. Will this be an issue? there isnt a rule about how low an exhaust can be. however it still must be safe to drive etc....this means if it bottoms out all the time under normal driving then that would fail Quote Link to comment Share on other sites More sharing options...
Hachi-ichi Posted October 30, 2013 Share Posted October 30, 2013 ah ok, it bottoms out on my driveway lip and generally only on really bumpy pieces of road, other than that I haven't noticed it. Quote Link to comment Share on other sites More sharing options...
