## Questions & Answers

**Q: For a 95 mustang do you need to do any modifications for fitment?**
A: No, no modifications will be needed but we do recommend control arms if you're going lower than 1.5".

**Q: Can I raise my car with these?**
A: Unfortunately no, this will only lower the vehicle. Will not even get your vehicle to stock height.

**Q: Do I need camber castor plates for this?**
A: These actually come with front camber plates already.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It fits!
  

*by R***N on Reviewed in the United States on September 5, 2021*

Fits good! Everything went together we'll. It's kind of confusing figuring out what height you want but it's nice to separately adjust ride height and dampening. Would definitely recommend this product if you're over the fence and kind of scared cause it has no reviews. Only had it a few days but will update if any problems.

    Avoid these, they fail!
  

*by T***S on Reviewed in the United States on April 9, 2024*

I purchased these for my 2006 GT. The installation was pretty straight forward. They have been on the car less than 8 months and less than 20 miles driven, the left rear shock has left a puddle of pretty blue oil under the car. Failed product, not happy...

### ⭐⭐ 2.0 out of 5 stars
