Hello professional guys/gals.

my car is lower is (under exhaust) height is 100mm
and
tyre now is
front 235/35/20 and back 245/40/20
Under bump road had touch i got abit headacre.

If I go grab put
Front 235/40/20
Rear 245/45/20
Will work front 5mm up and rear 10mm up?
Or change lower spring little higher?

If was you what should you do?
thank professionals for helps.

will increase front radius 6mm, rear radius 10mm
will throw speedo out and may affect abs/traction control
will read 4km/h lower than actual speed

Change spring height....I suspect the car would bump steer (ie having to adjust the steering wheel, when going over a bump on a straight road).....So lifting the car would eliminate this occurring and the exhaust hitting (ie make the car nicer to drive) and more importantly make the car roadworthy...(ie roadworthy being your personal choice and less stress on your wallet if caught)

@lout posting....He is correct....No need to have other issues crop up as a result of the tyre size changes you have suggested
