cletus Posted November 13, 2023 Share Posted November 13, 2023 Can use limit straps. You may run into issues with the spring being cut though- can only do that if the spring cup is designed for that ie the original spring has a end coil that isn't flat 2 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted November 14, 2023 Share Posted November 14, 2023 What is defined as a recognised spring manufacturer? Any ltd company that advertises spring manufacturing? Last time Alex did a write up on his spring modification adventures for the Viva he showed that he heated the ends, bent them down and then ground them to look OEM. I guess this would be illegal if detected by cert inspection? Quote Link to comment Share on other sites More sharing options...

yoeddynz Posted November 14, 2023 Share Posted November 14, 2023 I'll just put the old springs back in then. Save a lot of hassle. Then sort the height issues out later on. Quote Link to comment Share on other sites More sharing options...

A even better question is who tf give out wofs to a car that has strops holding the springs in 1 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted November 14, 2023 Share Posted November 14, 2023 Last car i ran on cutties refused to self centre. I think it was the crooked load on the top cup causing the thrust bearing to bind up. Wofs were a cunt. Quote Link to comment Share on other sites More sharing options...
igor Posted November 14, 2023 Share Posted November 14, 2023 Guy I went to tech with had an early 80s Sigma on cutties. Used to swap back to stock springs for wof day. Reckoned first time he swapped the springs it took him all day but after he'd done it a few times he got down to under two hours. Quote Link to comment Share on other sites More sharing options...
Bling Posted November 14, 2023 Share Posted November 14, 2023 No one cares. As for the actual topic of springs, just give Chamberlains a call, was a year ago I popped in so I don't recall the price for some custom springs. Wasn't cheap, but also wasn't more than one would expect to pay for someone to calculate the exact spring needed to meet the requirements you provide when ordering. 1 Quote Link to comment Share on other sites More sharing options...

cletus Posted November 17, 2023 Share Posted November 17, 2023 This is going to ruffle some feathers Basically, anything with an air bag, if fitted with an aftermarket front bar ie the thousands of 4wds in nz, has to be a frontal impact compliant bar 2 2 3 Quote Link to comment Share on other sites More sharing options...

cletus Posted November 17, 2023 Share Posted November 17, 2023 Just to note, this is not LVVTA that is coming up with these rules, it is NZTA . There has been a few things lately where LVVTA has tried to make things easier for people but NZTA has not wanted to play ball... ADAS systems, and any changes to them, is an example Utes, and typical modifications to them, seem to be a particular focus at the moment 4 Quote Link to comment Share on other sites More sharing options...

They seem a bit vague: "There's some evidence..." "Bullbars can cause airbags..." Would be interesting to see some of that evidence. It seems odd they focus on the drivers safety when you'd think the risk from bull bars is far greater to a pedestrian or cyclist and that adding bars to the front of a vehicle will affect any of the Vulnerable Road User safety features a vehicle has. Australia has done some research on this but it's tricky to get solid conclusions since the data from real crashes lacks certain information and the sample sizes are quite small. But generally it seems accepted that bull bars increase the risk to pedestrians. But it's hard to find much about how they affect they affect the internal safety systems, like air bags, of vehicles fitted with them. I think partly since some of those systems are quite new so again there isn't enough real world data and that studies on that specifically haven't been done. With all the things they could be doing/looking at, how does something like this get chosen as the change NZTA spend time working on? 2 Quote Link to comment Share on other sites More sharing options...
Nominal Posted November 17, 2023 Share Posted November 17, 2023 You could try asking NZTA / OIA? It could be a way to use the rules they have (safety systems) to back-in improving pedestrian safety without having to make a lot of new rules.
