Hi everyone,
So I’m trying to plan out my winter agenda for the 84 VW GTI that I bought this summer, and the main focus I have is a suspension overhaul. I want to do bushings, tie rod ends, ball joints, strut mounts, and ST coilovers (rebranded KW V1s with lesser finish specs). It’s currently BONE STOCK from the previous owners so I’m dealing with a blank canvas here. If I had to describe my intended usage of the car it would be infrequent autocrossing and weekend driving. I'm looking to autocross it purely for fun, I won't be trying to compete regionally. I have STS or FSP targeted as my likely class.
It won’t be a daily. I can handle a bit of a rough, somewhat noisy suspension but I’d rather not rattle out my teeth on a long drive. I want to lower it, albeit partially for cosmetic reasons, but most it will NOT be “hella flush slammed and poked”. I want a functional ride height that I can dial in for autocross too. That will probably mean that I’ll be at a reasonable drop most of the time and I will “show drop it” if I feel the desire to.
So I’ve ready plenty about how awful the late front strut mounts are, and based upon that I’m thinking about early rebuildable mounts or a 1.5" to 2" raised strut tower setup with better, rebuildable components.
What intrigues me about the raised mounts is that some people mentioned that you can obviously lower the car, but for a coilover suspension also maintain the suspension travel at the same time. For autocross this sounds like a great advantage.
I have a few questions about that though:
1) If I am going say 1.5” to 2” lower via this method, will the car be handling “better” without as much compression of the struts and springs as I would have if I were simply lowering it with the collars like normal? Is the handling and comfort going to be “better” because of that? I ask this because I’ve read enough accounts of people with coilovers (although mostly the cheap Raceland variety) claiming that when fully raised the car handles worse and has poorer ride quality then when lowered (stiffer of course).
2) And likewise, if the front is at near full travel capacity because of the raised strut mounts but the back is being dropped that same distance to level it am I going to create an imbalance where the rear is more compressed and stiffer then the front? If this assertion is true could it make the handling worse? Am I going to really amplify the 3 wheeling tendency around corners?
3) Given the above concerns does this sound like a bad idea for what I want to use the car for?
I can't honestly say that I have looked into putting together my own custom length strut and coilover sleeve combo but if this was actually a logical and useful mod for autocross I could see trying to figure out how to use this to my advantage to get more suspension travel.
