Vxr8 rear 20s

[nickwaiheke]

I'm thinking about moving from 275/30/20s to 275/35/20s on the rear
Anyone done this?
Does it fit well and any issues?

1. Why?
2. Should fit fine unless like me you have spaced them out to fill the arch. Increasing the dia slightly can get things close to the bumper/arch point but the wheels are do sucked into the arches stock I am sure you will be fine.

Just fed up with bottoming out at the back on some regular roads I use even going very slowly !

How do you mean bottoming out? As in the car scraping the ground, or hitting the bump stops? Either way, I can't see a slight increase in profile helping in a substantial way.

That much increase won't help you at all! Try looking at your ride hight and suspension. Mines low but on super coilovers set quite hard and have no issues.

Yes previously I would have agreed but changed to a different set on the front still formally the same size but gained maybe an inch and it's stopped scraping up front

Theoretically, they will give you an additional 13mm of ride height, but they will also change the gearing of the car. It's really not the best way to change the ride height, and I would recommend a spring change back to standard to do it properly.

Watch for the spring cups on the shock absorbers (if there are any) fouling the tyre.

13mm Plus the difference in tread depth between the worn tyre and the new one

As per others above I'd recommend changing your ride height if you're concerned about the ride height.

Changing the tyres will increase your gearing by around 4% and therefore blunt your perfomance in each gear by around 4%. The extra tyre wall should make the ride a bit more compliant, but it'll also bring a bit less precision to steering / handling.
