I'm probably going to be looking into bags for my sedan around next year as its impractical to have a car lowered at all where I live and I plan on keeping her for a long time and putting a bit of work into hense the decision

im factory ride height with after market 18x8f and 18x9r with 235/40 R18s all round (bit of stretch on the rear and none on the front)

i scrape front if i take it nose on, if i angle i dont.

with a full car load i scrape aswell, but most times im good.

Because???

Many people have done this and recommend it.. lowers by about 25mm without sacrificing too much ride quality.

I can't imagine lower mine any further. Don't know what ride height i'm on but it's stock and i'm scraping everyday i drive.

technically you are not factory ride height anymore because you are running 40 profile instead of 45. You are approx 20-30mm lower than factory with those tire profiles.

mine has always scraped.

back when i had standard shocks and springs with 18x8 +35 factory premium alloys and 235-40-18 tyres.... the standard springs had so much travel that the under engine plastic panel would drag along the ground AFTER bumps in the road... the worst suspension ive ever driven on.

now with 2003 model 350z shocks and springs with 20x8.5 +35 235-35-20 up front and 20x10 +42 265-30-20 stretched in the back..... i rarely scrape under the car, but always drag the custom front lip (its lower than parking bay concrete blocks.... an upright iphone barely fits ) and the rear muffler drags occasionally when reversing over driverway gutters.

have only slammed the chassis rails once.

and even with 250kg of fat people in the back seat, the rear only dropped an inch

fyi: the 350z shocks and springs originally felt way too stiff for my liking... but ive grown used to them and am quite happy with the ride. And theyre not stupid low either. Nightcrawlers is definitely lower than a slugs scrotum.

Tyre sidewall height of a 235/45 is 105.75mm. The sidewall height of a 235/40 is 94mm. Overall tyre diameter changes by 23.5mm but radius only differs by 11.75mm (axel to tyre edge) which is the amount the axel will be closer to the road.

    • @robbo_rb180 I already have a NEO head on the shitbox 馃槑 Just needs beehive springs so I can rev it past the 8600 rpm limiter, then again pointless too, turbo is out of puff lol. Wen da gods let me win lotto eh?
    • Everyone I know with a90 supra at time attack aren't having issues with 3-5 fast laps so far and one is decent powered one too. Saw a k24 swapped 86 with a 8hp70 and big slicks and aero which had no drama's at QR and Manton Park. I've stuck a 25 row cooler in my setup with 8hp45/50 in the hopes of keeping the oil cool as I plan on some racing next year that 20-30min sessions. I've also geared my car so won't be using 7th and 8th gear too. @Dose Pipe Sutututu just needs to get that samsonas in already and have that tassie guy fit a head and rev it too 11ty thousand rpm. 
    • My embedded systems thoughts have me sitting with GTS on this. Variation between same phone hardware, should be small. However, the internal "intensity" or "volume" amount that say Google passes to the app, will be quite different, as the underlying hardware will be passing different levels for the same volume to the Google OS. Until the app creator has had each individual phone, and set benchmarks and calibrations for each, the amount of error can be quite huge.   It can even be observed by using different phones, recording the same noise, and then playing it back, they end up soon ding different. A big reason for it, is even the different types of mics used in phones have different responses, and different frequency ranges. Then you need to get into the DSP, and the variations in those, their sample rates which then effect their frequency range, and then the quality of the DSP, and what type of hardware conversion they do to for the ADC within the DSP. Oh, and let's not forget at the low level phones are designed to cutout loud sounds. It's one of the reasons they suck in really loud environments (eg concerts). The louder you yell, the more you'll get cutout too Note DSP is Digital Signal Processor ADC is the analogue to data converter. I don't have any real data on what the variation would truly be, however, chat GPT says in general, their output is typically between +/-2dB to +/-5dB of what you're really measuring. So realistically, anything from 4 to 10dB variation is possible even with the same devices.
    • 'sif the error will be that low!
    • I do know where there is a fair few 馃槈
