Your looking at a double upgraded lower arm replacement for your multi-link suspension, are you sure you need this replacement piece with the extra features?
If your wanting to play with your car's suspension and make adjustments every now and then go for the upgrade.
If your not the racing type and won't be further modifying your car and just want a dependable regular ol rear suspension, I'd recommend the OEM without the fancy do-dads.
BTW my 1st generation model (87-89 only) came with those heim-type revolving end pieces on my suspension arms and I pitched them. Too much extra play and movement. Personally I want a stiff suspension, no flexing.
And yes, I read the "Advertiser Claims".
