slowsentra94 07-16-2007, 12:26 PM i recently looked at my strut towers and i read somewhere that 240's are siliconed together because nissan is cheap...and this lead me to my question does anyone have any writeups on specific points that the 240 chassis needs to be supported with welding or upgraded...basically which parts need special attention to when prepping the chassis. thank you paNX2K&SE-R 07-17-2007, 06:39 PM Actually I think its Elmers Glue :D What is the primary usage of the car? Steve has a cool writeup about using 2 part foam to add some chassis rigidity. slowsentra94 07-19-2007, 12:57 PM elmers glue is to0 expensive they went for the store brand water soluble nontoxic glue...i am mainly gonna use it for autocross and time attack...and drift from time to time...im just trying to find out what areas of the car i should weld to add strength to it...pics would help too...btw i dont know who steve is can u direct me in that direction with a link?

Just remember that Nissan engineers designed the car to have a crumple zone for crashes and stuff too, so don't go overboard and weld the entire car if it's going to be driven on the streets, or it's gonna be very safe when an accident occurs... slowsentra94 07-22-2007, 01:14 AM thanx for the info but do can u direct me towards a sticky or a website or just start a list and make it a sticky that points out specific crucial spots that sr20's need reinforcing in... sr20boostn20 07-23-2007, 09:31 AM all my strut towers are spot wleded and so are all the seems around them , but thats about it.
