I took mine off to replace it with a Nismo item. It took me about 10 hours to get off and a massive headache. Cut a long story short I had to put on and off both plneums twice each. The second time i pulled off the stocker it took me 30 mins to get off. Thats in a 33. A mate who owns a 32 (and is a mechanic) said 32's are harder due to having a slightly smaller engine bay! If you REALLY want a challenge... put the Nismo one on.
Its all a learning curve mate ive never done it personally but i have replaced the tubs on the GTR and altho it took me a while i know if i had to do it again i could do it in half the time cos i know wot to do it is a daunting task but if you want to learn get it done :thumbsup:
