Summary: I just want to say how happy I am with Speedway Motors. They make it easy to like them. From ordering the parts and really, when you have to return something. Simple, easy, and no bs. As for the control arms, their mounting holes are a little too big for the shock to mount to. You will have to take a file to it to make the shocks lower mounting fit. I would like to see them power-coated or painted
Yes, I recommend this product.

Great build quality, and amazing customer service/support Rated by Jaycon on August 07, 2024
Summary: The Team at Speedway Motors is unbelievable on their support for the product both during the purchase process, but more importantly the technical support after the sale. I had an issue with the QA1 Coilovers (sleeve fitment - bolt size was different). The Tech Team reviewed the issue with me, and then supplied the right fix to solve the issue without a second of quibbling. It was a great experience working with their knowledgeable staff. Something that's far too rare these days.
Yes, I recommend this product.

Spacers included not long enough Rated by Mr.C on January 19, 2023
Summary: Not a direct fit to the Speedway coil overs, had to use washers to take up slack in the cross bar of the shock, (4 thick washers on each)
Yes, I recommend this product.
