1992 FD3S chassis stiffening/refreshing
Hi all.
I own a FD3S and the chassis seemes to be too old now (year 1992 and 19 years old of age..). I am thinking to refresh the aging chassis and reduce as much flex. So I am planning to do spot welds on the chassis for refreshing the old chassis. My target of spot welds : 1- just to have 'new' chassis feel and solid handling on normal road since this is on-the-road car. 2- 70% will be driven agrresively on normal uneven poor quality roads and 30% track day. 3-to eliminate body flex. Can be easily seen when i jack up the car at one corner and creaking sound is everywhere.. I dont know if i have to weld the whole body or only at some critical point of the body to get the purpose as i mentioned above. I also dont know where is the critical part of the body to do the spot welds. As I know, the main area of spot weld are: 1)door jamb area 2)front windshield area 3)Rear hatchback opening and spare tyre well 4)Firewall 5)Engine bay, 6)suspension tower Front and rear.. How about: 7)transmisson tunnel area? 8)Floor area? Really need opinion from you guys on the sufficient weld areas to meet my target/purposes as stated above. Some of my friends suggested spot weld the whole unibody. But I am afraid it will be too stiff and hard for bumpy roads and sacrifice my traction or handling and crack the body over days. ( As i know, the chassis still needs some very little flex for good traction and handling). Please correct me if i am wrong...because i never involved in a professional motorsport, I just read in the internet.. |
