hi guys.. what are the differant options.. just purchased a 92 seville with what my friend said was a sls or base model? not the sts.. what are the differances between the two? the front struts the same? what is a good aftermarket strut for these cars? what size tire looks the best under these cars?

 

I know the differences from '93 and up .However '92 should be same as well but with 4.9L engine .
SLS is speed limited to 112 mph/180 kmh ,has a hood ornament,no fog lights or either optional,bumper has some chrome stripes ,less wood in interior .
In 93 and up main differences are different final drive ratio and engine code.STS uses Vin 9 , SLS Y
