If you search on this topic, you will find that one or more of the following 3 solutions will fix your problem....

- spark plug (gap/heat range). You will find coppers gapped at 0.7 - 0.8 mm will work best for you. For a street driven car with basic mods (FMIC, boost, exhaust, SAFC/PFC , etc), stay with a warmer heat range - 6.

- coils: measure the resistance accross all coils when cold, make note of it. Then meassure them again when hot. You will find faulty coils will have a different resistance to a healthy coil when warm.

- A:F ratios. Get it on a dyno to see what your A:F ratios are like where it pops. I'm guessing they will be extremely rich at that point. A SAFC will help you sort those out, or even better, a PFC to help with your timing issues also...

    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me  
    • That's my life. Past-Duncan has a lot to answer for
    • Yep four point harness. Mounted to a bolted in brace running behind the seats. Dont use it for daily driving tbh but good to have for when its needed plus it looks cool.
    • I had to double check the thread title r34 gtt offset advice lol. Thought maybe i posted on the wrong thread. 😂
