If you can, put your 275 up front.
After you mount the wheel, perform a lock to lock test of the steering wheel and make sure nothing is rubbing, then take it for a ride and try to perform some figure 8s in a parking lot and see if you have any rubbing.
You will have better front grip (less understeer) with the wider tires up front - at the expense of increase of rolling resistance which could decrease your gas mileage.
In a perfect world you would have a square set up (same sizes/tires on front/back) which would remove any...
Is it really a Z4? C'mon man - they made them together and went the separate ways.
For the price you aren't getting anything with this weight and power - its a great car.
All the new M cars are what 3800lbs plus? To me that is flat unacceptable as a "fun track ready" car.
Emira is lighter...
Illinois charges 7.5 Sales Tax on cars, and then you pay 151.00 dollars a year to keep your car registered by getting a new sticker to put on your plate - no yearly assessment on your vehicle.
I am paying 15,500 (yes fifteen) dollars yearly property tax on my 3 car garage, 3k sqft home...
Seems like it would be fun for giggles at first, but then you would eventually get sick of it and change it back to normal.....like many of the aftermarket exhausts people put on these things.
Where have you seen that?
I have seen a couple on an actual drag strip (not on the street using Dragy app) that were in the 10s but they were using Ethanol.
The whole motor and front subframe need to come out in order to do a turbo swap on those motors as well - and the trans (like us) needs...
I would be less worried about your warranty and more about your emissions testing - without a tune (and possibly with a tune) you will not be able to pass and register your vehicle.
Without a tune you will have a check engine light on the dash and various catalytic converter efficient codes...
As others have posted above - you will probably need to be running an Ethanol blend fuel or perform some good weight reduction (seats, interior, etc) on 93 octane.
Most folks running 10s are running E50 or so.
Because you have a '21 Supra - you should wait for BM3 to come out with their Gen2...
You can search here, but many of the open filters that give you the noise actual hurt your Intake Air Temperatures - the OEM box already has an opening for cold air. You will probably get better throttle response, but pretty much no gain in power.
As member Bushido posted, do the following and...
Interesting - I didn't think any car today came without parking sensors - let alone on a Toyota Halo vehicle.
Also the spoiler on your car is aftermarket as well - it was not offered by Toyota.
Completely understand! Keep up your good work - better to release a product that works and fully tested then have to go back and remotely troubleshoot!
