Overall Assessment

Customers appreciate our product for its perfect fit, particularly on vintage models like a 1985 Monte Carlo SS. Its easy installation, good workmanship, and quality have been highlighted as commendable features. The product has also been praised for being an exceptional value for money, with users willing to repurchase. A few users, however, experienced durability issues during races, but this seems to be an isolated case contrasting to the overall strong positive feedback about the product's performance and quality.

Would not buy this again. Very cheap.

I have purchased many products from speedway and this is by far the worst. Both uppers came apart, the clips popped off and both ball joints bent. They were only on the car for one race that didn't even get finished because of rain.
