I've done a lot of read up in the DYI section and i must say you guys are fantastic.

While reading across those thread, "flat spot" topic keeps popping up now and then. I would like to know what exactly is a "flat spot"? I am driving a R33 but my car jerks if i don't warm it up properly but if i did, everything seems to be fine.

FYI, my R33 is light modded with:

ARC FMIC

single plate racing clutch and flywheel

denso iridium 8 plugs

adjustable suspension

actually all these were done by the previous owner. any idea why my car could be jerking if i do not warm it up properly?(at least of 10 mins warm up)Could the plugs be too "cold" for my car or is it some other problem.

and please do explain what is "flat spot".

thank you very very much!

      Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
