Rich83 2 Report post Posted December 27, 2018 Hi guys I’m considering getting a carbon siebon bonnet for my 86 however I’ve read in a few places that the lifters can damage it. Can anyonr explain why this happens and Is there a way round this? thanks Rich Share this post Link to post Share on other sites
Lmc 27 Report post Posted December 27, 2018 Depends on how strong the lifters are. carbon bonnets are basically fibreglass with a carbon skin so there not as strong as the standard bonnets. that said i had carbon bonnets with lifters on my rx7 for 5 years and on my 350z without any problems.
