Hi Guys.. got myself a set of 350z 18x8 track wheels to replace my 20"... Couple of questions after speaking to my tyre guy ..

1) He recommended running 245/45 18 front and rear... I read some earlier posts about not doing this as it might interfere with the car's VDC controls?

2) At the moment, I got the Ken Style Front Bumper on Stock suspension and as it is right now, I scrapped almost every time! Dropping to 18's .. even with the increased sidewall .. means dropping the car lower??

By the way PN-Mad, Front Sways are Hard and Rear Soft!

Thoughts from the experienced folk out there?

Thanks! So, running 245s all round is ok for VDC. Is that good however for handling/driving? Or you won't notice anything?

OEMS 225/50 17" front and 235/50 17" rear ...

Using http://www.alloywheels.com/Tyre_Calculator, it appears I need to go 245/40 18" for Front which gives me a -0.29 difference, which should be ok.

However for the Rears, using 245/40 gives a -1.77% and 245/45 gives a +1.82% difference.

Which combo is best?

I run 225/45/18 front and 245/45/18 rear on OEM 18x8 coupe rims. I now get at the limit understeer so going 245/45 front and rear should fix that up and perhaps the tail more likely to kick out first than the front. But with that amount of rubber on the road grip levels will be higher than stock so unless you are on the track you probably will never notice it.

1. those tyres will be fine, it won't affect your VDC.

2. It'll probably still scrape lol

Wait, what? What tyres can't we run? Sorry im pretty new and am not aware of wheels effecting the VDC. Are there any writeups?

      What an awesome idea to fit the facelift Lamborghini Diablo headlights. They are a perfect fit!

      An update regarding the registration with the DVLA I sent off the paperwork the day after I collected the car from the port, two weeks later it was all returned with a letter explaining they have rejected the application. This was because the cheque was £20 short for the road tax (I used a price list I found online). Nevermind it is what it is, it was sent back to them the following day with a new cheque. Fast forward another 2 weeks or so, I called them for an update to be told it had been rejected. Yesterday (16th September) I received the documents back along with another letter, this time it was because I didn't put an X in one box on the V750 (personalised number plate certificate), which declared that I had the rights to the personalised number plate. Why this wasn't mentioned in the first rejection letter, I don't know, but it could have saved this headache. The documents were sent back today, so fingers crossed third times a charm and it'll FINALLY be registered on the road just in time for the bad weather (woohoo!) To cheer myself up I lowered the front 25mm, was sick of seeing it sit like a monster truck. No idea how much clearance I'll have getting on and off the driveway, I'll worry about that when I can actually drive it

      You're going to miss not worrying about rust in the strut towers like the Skyline shitboxes out there

      A few little updates that weren't filmed due to not taking long to do or not interesting enough for their own video. My new K&N Air Filter arrived, I went with an RU-4180 which matched the dimensions of the universal cone filter the car originally had.  The battery had gone flat, while that was charging I tidied up the spaghetti wiring at the bulk head and down the sides of the engine Next job was to swap the stereo The Kenwood harness had the female ISO plugs cut off and the male ISO plugs cut off the adaptor loom and joined with bullet connectors. I ordered in a repair loom through work and re-did it all. New Kenwood unit installed (Android Auto, DAB, Bluetooth, Reverse Camera) The bonnet/hood gas struts have been poor since collecting the car. I couldn't find any suitable replacements locally so took a chance on a pair from AliExpress.  The originals don't use a retaining clip to secure the cup onto the ball fixture, would explain why I struggled for 10-15mins trying to pry off the cups. The ball fixtures unscrew using a 12mm spanner, new ones are the same size. Sadly no photo of them fitted, you're not missing much lol The dished Momo steering wheel got replaced with my Momo Tuner, turns out I ordered counter sunk bolts for the horn trim ring (like they normally are for the steering wheel) instead of allen cap (flat seat)  A terrible photo of a Quaife style gear shift knob I've had stashed in my tool box for many years after purchasing the incorrect thread size (I can see a pattern emerging with ordering incorrect parts...) Also threw in a cup holder and a (empty) Boss Coffee can, because why not

      GT-R clearly the better choice! The 300 is certainly not insaly fast but has a decent amount of poke. Does a nice little drift around the corners with a decent amount of throttle. It's VERY predictable in a slide too.  Feels so progressive! People probably presume there's a 25 year old driving it based on my behaviour this week! 🤣
